Filters, oil, fuel sample etc. My thought process was something was heating up and shutting the fuel off. Bad fuel would make it run crappy all the time, clogged filters would make it run crappy from the start up. I asked for help and will follow your steps first to see. If not then will look at fuel pump, sensors and solenoid. Wrote: Richard beat me to it...I'm leaning towards lack of fuel.
My culprits, in order of appearance ;-)...or at least order of what to check first:
1. Filters clogged - change them (and yes...I've seen new filters clog when you've got bad fuel!)
2. Bad line or fitting letting air in line, etc. - pull a line and test
3. Water in line/tank - look at glass, draw sample
4. Bad fuel (algae, gel?) - pull sample, treat tank
5. Fuel pump - test pressure, replace pump
This would be my steps to go through.
I had a buddy of mine that bought a diesel truck, it had over 500k miles on it and it was having a recurring fuel delivery problem. The dealership did almost everything to fix the problem, even replaced the engine computer to eliminate it. What was happening was every time the fuel got near the bottom of the tank, crud in the tank would gather around the in tank filter and it would then run like crap until you filled the tank up. Finally they pulled the tank and cleaned it and all was well. Moral of the story is that clogged filters etc can act funny, they are not always just plugged up, the crud can move around and plug them one time and not another. The list provided is what I would go through and hopefully one of those is your issue.
