COMMON FOR THESE TO HAVE IGNITION MODULE PROBLEMS, HAS THIS PART BEEN REPLCED IN THE PAST, ALSO COMMON TO FAIL UNDER A "HOTSOAK" (VEHICLE DRIVEN THAN SHUT OFF), UNFORTUNATLY TO CORRECTLY DIAGNOSE THIS VEHICLE THE PROBLEM WOULD HAVE TO BE OCCURING LONG ENOUGH TO VERIFY IF IT IS LOSING FUEL OR SPARK. HAS THE CHK ENGINE LAMP EVER COME ON SINCE THE PROBLEM HAS BEEN OCCURING? ONE THING YOU COULD DO IS PURCHASE A TEST LAMP, AND WHEN THE PROBLEM HAPPENS-PLUG THE LAMP ON ANY METAL ON THE ENGINE AND PLACE THE PROBE 1/4 AWAY FROM A PULLED OFF PLUG WIRE (BETTER TO CHECK AT COIL) IF SPARK JUMPS ACCROSS TO THE PROBE ON THE TEST LAMP WHILE SOMEONE IS CRANKING THAN WE'VE VERIFIED THE VEHICLE HAS GOOD SPARK WHEN THE PROBLEM IS OCCURING, AND IT THAN HAS TO BE FUEL RELATED.
