    You mean you already verify if there is a stored trouble code? Check out this link http://www.extreme-check-engine-light-codes.com... to have an idea how to extract stored trouble code in your vehicle since it is equipped with OBD I.

    Replace the distributor ass'y with a new unit, not a reman. I have read what you said it is doing and I have read what you replaced. My answer is based upon the assumption that when the engine does not start, there is no ignition spark present. The actual cause of your stall / no start is a bad distributor shaft which can be confirmed as long as you check it during the time that it will not start. Since the engine recovers enough to run again after some period of time you will have to perform your diagnostic test expeditiously. using a Digital Volt - Ohm meter verify at least 700 mV of AC voltage at a fast cranking speed from the pickup coil. The pickup coil that you already replaced is not the cause but rather the permanent magnetic reluctor that is permanently attached to the distributor shaft that spins within the pickup coil you replaced.
