I have a similar problem with my Jimmy. When I first turn it on, I have to let it run for a few minutes, otherwise pushing the gas pedal just causes the car to lurch, like it's starved for fuel. Also, even if I let it run for a few minutes, I cannot get on the interstate and go straight to 70mph. The car will lose all mechanical power. I have to pull over, let the car sit, let it run for a few minutes, and then get back on the road. I lose no electrical power. My lights and my radio work just fine. I am confident that it is a fuel problem, I am just unsure of what the problem is specifically.
