Thank you so much for the info. I found the 7812 that powered the amp to be
bad. A $2 radio shack part and a little time, and my RX-5502 is back up and
operational. Mine was shutting down exactly as you described and after
replacing the 7812, it has played music for over two hours and is still doing
great.
