I have a 90 Buick Century with 3.3 L V6, 163K miles. Engine has been running well until all of a sudden it lost power and engine stalled. I can restart it if I wait 30-60 minutes. It runs great and then will stall again within about 2 minutes. If I try to start it up up right away after it stalls engine won't even crank over - giving the impression like you have a dead battery. But waiting long enough the engine starts fine and runs for no more than 2 minutes.
Anyone have an idea what is causing this? It must be some electronic control component.
