Couple of simple things to look at:
Do you have anything stacked on top of the 11R? It could be overheating and shutting down.

Do you have it plugged into any kind of power conditioner? That would be a good thing as most municipal AC power has all kinds of crud on it, not to mention what's also on the same side of the line in one's house.

Thanks for your help, I have it in a 2 sp. rack for live work, had on isobar ultra conditioner / without same result. house currant is good. Didn't notice much heat. I will take it out of the rack and try it. Unit power supply maybe ? Thanks again

You have a 2 space unit in a 2 space rack? No breathing room I bet. My 11R gets very warm after a couple of hours of usage let alone after being on 12+ hours in my studio. Mine's in a 4 space rack with nothing in the space above so there's some place for the heat to go to. Remember basics laws of thermodynamics that heat rises.

It could be the power supply inside but I'd take it out of that rack and let the thing breathe. Heat is the enemy of electronics.

Iam testing that now. thanks for the help.

Very strange. One last thing to try before trying to get it fixed by Avid - can you leave the unit powered on and connected to nothing other than an AC outlet? Like overnight maybe? I know I'm grasping at straws but wondering if something's coming in that tells it to shut down. When you run it is it also plugged into a computer via the USB port?

I will try your suggestions. All other tests were with USB plugged in computer. Thanks again

Unplugged USB, midi, main outs, Played thru gtr input phones out for about an hour shutdown and started again. It takes about 15 seconds for the reset

Well you've tried everything I can think of - guess it's time to try and get it fixed if you can find someone to do so.
