My 2014 F150 was hauled to the dealer yesterday afternoon on a flat bed tow truck. My wife was headed home from our son's house. She was going up a hill on a two lane country road. It lost all power, and was just able to get up the hill going about 5-10 miles per hour. The wrench came on at the same time. It will be either tomorrow or Tuesday before they give me any info on what's wrong.

By the time I got there, had been at the doctor's office, I guess it had settled down, because it started right up when I tried. However, since AAA had been called, we waited for it and took it to the dealer.

Fuse 27 most likely. Google that and you'll know more.

I looked up Fuse 27. That might have been a possibility, except in an hour, I was able to start the truck. If it were the fuse, I wouldn't think the truck would re-start at all, until the fuse was replaced.

could the fuse be tripping?

The fuse doesn't blow, the plastic socket around it melts and the contacts on the terminals will spread enough to break contact, once it cools down it makes contact again allowing a restart. May not be your problem but it's where I would begin to look.
