Somehow that doesn't surprise me.. My car acted up last year at an all Pontiac show, when it was time to leave. Twice it cranked over and wouldn't run, third time it caught and ran, but the starter drive gear wouldn't disengage from the flywheel. Started up normally on the fourth try, so I drove it home and replaced the starter. Ran fine for about 75 miles before acting up again. Turned out to be a faulty fuel pump relay.
Gremlins always seem to show up in pairs, or groups of three with our cars..
