My 1991 Pontiac Bonniville 3.8 will start and run and reach operating temp about 5 min. Then it will stumble and dye. If I wait for a few hours it will restart and the cycle continues. I replace the ingnition control module and know it runs better and did not dye , however when I turn it off and try to restart it will not start. If i wait for a few hours it will. I checked fuel pressure its Ok I checked coils for spark and they had none.What is the cause and why ??
