Sounds almost like my problem. Here is mine. Full tank of gas. Started to lose power like the gas pedal turned to mush and then the car died. Started up again and went a half mile and then died again and could not keep running. Was bucking and acting like mis-fires. Had it towed home. In the morning it started great and I drove it about 2 miles and it started doing the same thing. I replaced the fuel filter since I don't think it was ever replaced. Filter seemed OK...but who knows. Sprayed some starter fluid in the throat of the manifold to help it start and it ran long enough to use up the starter fluid and then died. Had it towed home again. Rolled it into the driveway and hit the key and it started just fine again and then after about 2 minutes of idling it started surging and then died. I then replaced the plugs, wiring, cap and rotor just because and it didn't change a thing. I suspect the fuel pump but I do not know how to check it and if it is bad how to change it out. This is a 6 cyc engine. All the hose etc. look fine. Don't see anything pulled loose or tweaked. My friend said to maybe drain all the gas out and put in a fresh tank since it could have water. I put two bottles of water remover in the tank and that also didn't change anything. Any ideas or explainations of how to test fuel pump pressure etc.?
