Hello all,
Long time reader first time poster here. I wanted to see if anyone could point me in the right direction with this issue. Its only been happening very recently and my receiver has been shutting off during volume spikes. Any idea why this is happening? Thanks in advance for the help!

More often than not caused by a loose speaker wire from one post touching another post.

Which speakers are you using? Your avr I think is not stable at 4ohms. If you are driving a tough load; the impedance swings below 6ohms during demanding audio passages would demand high current from your avr, which it cannot provide. The internal protection circuitry on 2311 may be kicking in and shutting it down.

Darn phone. Submitted the post while I was editing it. Yes it sounds like that is what is happening. I'm using deftech pro1000s as the front stage and pro 800s as the rears. I've had this setup since early 2011 so I can't imagine its the speakers. I just checked all my connections. Is my received going out?

My computer or my bluray player. It will do it on cable as well but not as often and depending on how the sound is encoded.

I guess the question is "what does the receiver display say" when things are happening?

It doesn't display anything really. It shows the surround parameter I'm running and then during demand audio passages ( seems to be related to volume as well ) the receiver shuts off and the power button flashes. I'm guessing the receiver is going out but I want to get opinions here first before making a decision on what to do.

OK.... but the flashing power button IS trying to tell you something. How fast is it flashing (ie. how times per second)?

Try putting a 4" RadioShack fan on top of your receiver above the heat sink. It may be running close to its thermal protector and a spike could trigger it. This has work for me on an old Sony es receiver. Just a thought.

Hey guys, so I think this issue may be related to heat like the previous poster suggested. So haven't really wanted any movies in the past week and no issues. Watched world war Z yesterday afternoon and the received cut out again. This time when it did I made sure to count how many times the power button flashes. Upon shut off it flashes until you turn the received off ( I let it go two minutes then hit the power button ). When I turned it back on it flashed on 10 times. Any thoughts on this?

As was posted earlier ... it's now how long the light flashes as it will continue to flash, rather it's the frequency of the flashing that should be noted ... a slow flashing (ie. once/2 seconds) would mean a ventilation issue while a quick flash (ie. 2x/sec) would mean a loose speaker wire, running low ohm speakers to loud, or amp failure.

Thanks for the help. I must have misread the post. I would say it was flashing twice a second. I'll get it to do it again and actually record the frequency.

More important to check the possible issues related to the flashing.
