Thanks for the input. Could you tell me how do I check the crank position sensor? I have not driven the car lately, except to let it idle till the engine shuts down after I threw several parts at it without avail. I just don't know why the ignition system shuts down after idling for 15 minutes. Could it be the computer? I saw two of them behind the battery, next to the OVP relay. Which one may be the culprit, if it is at all. Frustrated.
