This is a long post, story-style...

I'm very upset to be posting this, guys, but I'd love input & to alert you of an issue that left me & family stranded. Also, I'm very self-aware and am open to all criticism regarding lack of planning here, I want to learn from this one.

Situation:
My in-laws rented a cabin in the foothills of Northern California (mountains have experienced the most snowfall in 50 years). Arrived Sunday night, the truck was phenomenal driving through the snowy roads. Through a series of wild events: immense snowfall, downed trees, needing medicine for my 11-month old I needed to leave the cabin before the roads were plowed. The driveway into the cabin was long and steep (10-17% - my estimates), but on day one I was able to drive up and park at the top.

On the morning we wanted to leave, I started the truck in the flat, snowy spot it had sat for two days - it fired up without any issues. I drove forward and wanted to back up to a spot that was easy to load the bed. However, the tires were spinning (in reverse, uphill) and I was with my in-laws who are relatively incapable (not saying that I am) in snow situations, so I was impatient and left the truck running, pointed downhill (Mistake #1). It's important to note that the truck had 1/3 of a tank (36-gal) when I began the exit (Mistake #2). I went inside to help my family pack, when I walked outside after 5-10 minutes, the truck was off and my inlaws noted that "it just died" - I blindly excused the comment as I was rushing and figured that it had hit the 15 minute auto-shut off (Mistake #3). During this time the truck oddly continued to run all accessories on battery alone, I thought that was the issue later, but I don't think it was.

Roughly 15 mins later, the truck is packed and I'm ready to go. I Remote-Start the truck, fires right up, I enter, Push Start and the truck sputters and dies. I attempt to start the truck 2-3 more times with the same results: Starter works for 2-3 seconds, truck fires, no throttle response, dies. It ultimately gets to the point where it doesn't fire, Starter is still working. Also important to note that I am not mechanically inclined (had an LS1 Firebird in high-school and wrenched on that, but nothing since) and not to mention the underhood of these trucks look more like a robotics factory than I remember. I briefly attempted to look up potential fuel-related fuses, but unfortunately was without enough service to load any useful pages. I need to admit, I was stressed out and the primary priority was getting the baby out and home safe. So, we'd thankfully dug my father in-laws Chevy Tahoe out earlier in the morning and left it at the top of the only plowed road - we hiked the baby and limited items out and drove home. Left the Tremor at the cabin.

Next Steps:
I need to figure out how to get the Tremor out.

After reading several other forum posts, it seems like fuel delivery issues due to the slope of the tank may be an issues, see here:
https://www.f150forum.com/f118/f150-failure-start-incline-412262/ -- "Well documented on the forum. It’s happened to me as well. Typically it occurs if you park on an incline nose down. I’ve never had it happen parked nose up."

The road to the truck is currently unreachable for any local tow services, likely to be a couple of days before the situation improves.

Plan of Action:
My plan is to drive back in two days with a buddy (who is a mechanic, with F250 Tremor) with the following:
15 Gal of fuel
Spare Battery
Jumper Cables/Jump Pack
OBD2 Scanner
Misc Fuses

Hope #1: Adding an excess amount of fuel will allow the pickup tube to pull enough to keep me running and get me down the driveway

Fall Back #1: Attempt to get the truck in Neutral and muscle it down the driveway -- someone please tell me if this is too dangerous
- - How do you get these new trucks into neutral without it running?

Fall Back #2: Hope that the roads are clear enough for a flatbed to hook me up and take me to a local dealer.

As noted, please send suggestions, ideas, "you're an idiot" comments.

Crazy story, sorry that happened.

I'd imagine you can get it in neutral by just turning on the battery power without the actual engine, like any other car with electronic shifter. Though not sure how you'd be able to push it through snow unless you dig it out and it starts going down on its own with you inside to steer and brake, though sketchy since you wouldn't have gas to counter a slide if that happened.

Just using logic I'd guess that the small amount in the fuel tank is just not able to reach at that angle now that it has sat that way and the fuel in the lines ran out, but it can't refill the lines to deliver to the engine in the position it's in. Filling the tank with the 15 gallons should start it up. If not, I'd probably wait for a tow to he safe, but thats me.
 
Is there a way to get it into neutral and onto a flatter area? I think you are on the right track with the fuel, battery and other supplies. That's what I would do.
As far as putting it in neutral and coasting down the drive way - you'll have to be the judge of that. Its hard to tell how sketchy that would be without seeing it in person. Keep in mind that you wont have power brakes or steering (i dont think) if you choose to go that route.

Yeah, the more I think about this option, the big risk seems too likely.

Thanks for the input/confirmation, guys!
 
Sorry to hear about your troubles and certainly learned something myself about things to do/not do!

This is particularly scary when driving in similar conditions and losing power, especially when offroad. I will be doing my best to not let the tank level run down, but will also be more seriously looking into having some spare fuel onboard, just in case. While I can appreciate the difficulties of designing a fuel tank, I'm surprised that there hasn't been a simple solution (such as a tube) that has been engineered to the "downhill" end of the tank which would allow the fuel pump to access the opposite end of the tank to prevent the loss of fuel or two pumps. I get that fuel pumps cost money, but it isn't like they wouldn't pass that cost onto the consumer. Or include a reserve tank that is in line with the main tank.
 
Anyone have good solutions for carrying extra fuel that is more intentional than putting a jerry can in the bed?

depending on the amount some built right racks could hold a few fancy jerry cans or get a small slip tank.
 
Glad to hear- and glad you got it sorted out, sorry you were the Guinea pig for the rest of us!
 
Glad you got it sorted. This same thing happened to me once in my 2013. Parked nose down with a little under 1/4 tank on my 36 gal tank, idled long enough to run it "dry" and essentially was out of fuel. Added 5 gallons and got it running. Sucks but I learned my lesson.
 
Closure: 5gal can did the trick - wild how temperamental this was. I ended up putting 10gal to be safe and drove out without any issue.

Learning lesson for all of us!
So how much gas was actually in the tank when the problem occurred?

It was somewhere between 1/4 and 1/3 - so I'm estimating ~9gallons, but given the decline and leaving the truck running, that ~25% of tank capacity is what prevented the pump + pickup from pulling usable fuel.

Upon thinking about it, I think I would have been okay if I hadn't left the truck running.
