IF this is a 5.3, check the fuel pressure regultor, they had a leaking problem.
What brand of fuel pump? I stay with Delcos on these. Too many problems with aftermarket pumps. Bad from day one. Check the fuel pressure with a gauge that runs from the port to a gauge. Duct tape the gauge to the bottom of the windshield and run it, observing for change in pressure when problem occurs. This should help eliminate the pump, filter.
