Our 2008 6372 Supernova gave out during our spring break trip return trip from Florida to Maryland. The same symptoms everyone experienced with idiot lights and buzzer indicating a problem. We would pull over and shutoff the engine for 10 - 15 minutes and restart the coach. No lights or buzzers. Off we would go until the lights and buzzer kicked in - we limped back into Maryland for a very long drive back.
The coach was repaired by a local International repair shop - Capitol Cities International - good place by Annapolis, MD and they swapped out the controller unit with a rebuilt unit. Good Sam's covered most of the cost of this repair. I haven't had any problems since this repair but now I won't be suprised when if it happens again.
