It turns out the unit had dumped all of my menu settings. It was just as if I had turned it on for the first time, and had to pick which inputs go to what and also had to tune all the radio channels again. I now have it back to where it was, and it has been running fine for about six hours.
I hope this was just a momentary software burp or something, and not a sign of more problems in the future. Just wondering if anyone has heard of anything like this. If not, then you heard it here first. Maybe all those electrons just get confused once in a while.
