Welcome to the forum.
Any codes? Might get a scanner that records data while you drive. I have a copy of Diacom software that you can load on a laptop and connect the cable to the ALDL socket and it records all of the ECM inputs to the laptop. And if an event occurs while hooked up and you're driving, you can hit the space key (If I remember correctly) and it saves the preceding 30 sec of data so you can see what happened.
It works for OBD I or 1995 or earlier vehicles. Used it when troubleshooting my '87 IROC-Z which I sold. Software is yours for $75 (I bought it for $300 eleven years ago).
