I agree. A common problem with these trucks also is the pickup assembly inside the tank breaks off. It looks like a shower head. If that happens, you need to keep the tanks pretty full or they will suck air and not pickup the fuel when the tank gets down low.

I wouldn't necessarily think so. I would think that if the intank pickup busted off all the air when do it prevent or reduce the flow going into the system. It would only be an issue when the truck started to get lower on gasoline.

How many miles on the truck? And is the injection pump gray? If you have more then maybe 160k on a gray (original) pump it may be getting weak when it gets warm, that would explain the fact it starts again once the pump cools

When it dies and won't start, go out and push on the shrader valve on the filter head. If it squirts fuel, then possibly you do have a injection pump problem. Crack one of the injectors loose and see if it leaks fuel when you crank it.
