see question above. Sounds like what mine was doing, replace the distributor cap & rotor. I'm not certain at all, but I've been doing some research. Does your PGM-FI indicator light up on your dash board after a few minutes of driving? If so, it would be related to the main relay. Apparently over time the main relays become un-soldered due to heat and stop responding properly.
