I have a 1985 pontiac fiero. Rear wheel drive. 2.8lt. V6. 230,000 km. Auto. The car starts just fine. Will run for about fifteen minutes. then just shuts off. It will start again with a boost. What might this be caused from? I've replaced the distributor Done a basic tune up. Ran a diagnostic, which gave no trouble codes and had a mechanic look at the fuel pump.

Could be an ICM heating up or a failing fuel pump. You need to check for spark to rule out the ignition system. Then we'll go to fuel.

Good Luck
