Check the fuel pressure. It may be loosing its prime.

My Jimmy GMC 2000 has the same problem, I only get 50PSI when I turn the key, when it is started and running the fuel pressure gets lower if I idle it higher. After I shut off the jimmy my fuel pressure slowly goes down to zero on the gauge. I need some help here. Changed the fuel filter, fuel pressure regulator also.
