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

And then when gas is low in tank it stumbles driving down the road and also looses power at about 4000 rpm just stopps pulling

Ok, did you check the pressure

Roy

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.
