just read this and thought of one other thing.  What kind of power drop do you have at the amp rack?  I don't know the current draw of this particular amp, but if you have your whole rack into a 15 amp edison outlet, then could the whole rack not be getting enough power?

If he doesn't give the amps enough power the breaker would trip and the amps would stay off. If you read a little closer they are going into fault mode! Which normally would mean that there is a short somewhere. That theory only would work if it was tripping the breaker every time a loud section comes in.

This may also sound as though the amps perceive a brown out condition and shuts down. Monitor the mains voltage. Perhaps the mains can't push the power needed!
CE4000 are protected for a brown out condition. The reference capacitor (.47uF) at the brown out detector on the main board has been seen to be intermittant if at all faulty and replacement appears necessary or the amp stays off!
