I had that same problem with my 92 p/u.Does it stop if you put your foot on the brake?If so,it`s possible you have a short somewhere between the brake stop switch, the brake lights,and the computer.What happens is when you`re driving and you apply the brakes the switch sends a signal to the computer to cut the flow of fuel.If you have a intermitent short in your braking system it could be sending false signals to the computer when your foot is off the brake(or vice-versa).I found a bad ground on one of my brakelights,cleaned it up and the problem stopped.Good luck
