Truck has been running perfectly. Today, on the way to work, truck lost power. Give it gas and nothing. Pulled into a parking lot and sat for a minute or so. Started truck and it ran and idled no problem. Ran fine and decided to chance it getting one more mile to my office. Turned a corner and it died. Truck starts, and dies. No Check Engine Light, no codes, nothing. Checked Fuse 27, good. Replaced anyway just in case. Fuel pump relay good. Truck will consistently start and then die. Then thought maybe gauge was telling me I had more than I did. Added 5 gallons and no change. I feel like I'm hearing the fuel pump prime so I think its coming on and is good, and still think it wouldn't start if it was the pump.
Could be trash in the line, or the fuel line collapsed somewhere, but any other thoughts?

 

Sounds to me like a clogged fuel filter. If you were really low maybe you sucked some crap in from the bottom of the tank.

Well, in my frustration at the situation, i did not post the specs. Apologies. 2014 150 Screw, 5.0L V8, 4x4, 194k miles. Maintenance schedule followed religiously.

So, truck sat overnight and most of the day today. Went back to it today and started it up. Died. Started it again and it stayed running. Hit the gas and while it wanted to fall on its face, it revved up. Revved it up several more times around 3k rpm and eased off. Kept running. a little rough, but stayed running. Maybe bad gas or maybe trash in the line finally cleared through? Still no CEL and no warnings on the display. Afraid to move it too far. Thankfully its in a parking lot so I can move it around that lot some.

Any thoughts?

 

This ended up being the throttle body position sensor. Changed out the throttle body and it started working right.
