What is your question?
Have replace many sensors, new full pump, new fuel filter, new fuel tank. After 10 to 15 min run time (engine warms up) fuel sys shuts down until engine cools down then same process agin. Have had several GM and general machanics check out, but has become a head scratcher.

Any codes in the system, like a Service Engine Soon Light? Can you prove that it is a fuel problem, that is do you have a fuel gauge on the engine and actually see the fuel pressure drop off to zero?
