Welcome to the forums.
It's possible the ignition control module is faulty, or has dirty/corroded mounting screws, or is loose. I don't have a 1992 Service Manual; the 1993 manual has a detailed procedure for testing, and I cam across the ignition control module possibility. Other ideas: bad ground or power to ignition.
Good luck to you.
