Intermittent problems are the hardest to find. Suggest checking your fuel pump relay. I had one fail intermittently causing the fuel pump to appear to be bad...... New pump and few days later back to the same thing!!! The pump was due for relacement anyway with the fuel sock rotted like Sidewinder's photos show.
It took OVER a year to finaly track down the problem. As soon as that relay opened contacts and reclosed when restarting the engine it ran good till "X" amount of time later(which could be months!) Finaly one day it hard faulted, I found it with in two minutes while on the side of the road with no test equipment at all(meter or test light) A small jumper wire bypass got me home to where I have 10 of them on hand but none in the truck.... Now I do keep a few relays in my truck along with fuses too!
