Mine did that once, scared the s*** out of me as I thought I had blown the engine even though it was still running. Shut it off to check it over and found nothing. Restarted it and it has been fine ever since (happened about 5 years ago). I always wondered what the cause was and nobody else seemed to have had it happen to them at the time.
