I am taking my truck to the dealership tomorrow. A couple of weeks ago I went on a long trip and at one point I could not accelerate. I put it to the floor and nothing happened for a couple of seconds then it kicked right up and ran. It did this about three times and hasnt done it since. But I have been noticing when I stop or come to a red light it almost feels like its going to die, but in never does. Seems to have plenty of power just at idle seems kind of shaky. The power loss only happened a couple of times. Any ideas on what it could be. Thanks for the help in advance. I also change the fuel filter every 5000 so i dont think that is the problem.

Thats the way my truck acted when my lift pump went out. Not good to run it so long like that though. I bet the injection pump will be going out right behind it. (Mine did)
