It just strange that it cuts out any time it feels like it. Like i said could be 5/ 10 /30 mins or over an hour. If it was the speaker cables touching or something around that area i would hear a buzzing or crackling or something i would of thought. Can an amplifier cut out if the audio interconnects your using - interconnects for stereo music use, have been damaged etc.
just a return reply to john duncan . I'm using banana plugs on all of the speaker terminals and speakers.But the other day i took them of the back of the rear speakers so they are now bare wire, only on the back speakers though not the amp.

If you have a day or two spare then remove all the cables from the amp and leave on for a couple of hours, (assuming it doesn't trip off) plug in the front tree and run for a couple of hours, (again if it doedn't trip) plug in the surround speakers and run for a couple of hours.
If it does trip at some point remove the cables again and then go one speaker at a time.

Good idea actually. From what you describe it does sound like the rears are more likely the cause of problems, take them out and run with just the front three and see if the problem goes away.
If it does, then the rears are the problem. If that's the case, do the reconnection stuff we've discussed already, and if it's still a problem then -as already mentioned - it could be the wires or the speakers. Difficult to try 'new' speaker cable with such long lengths but it might be worthwhile trying the rears with long runs of cheap two-core electrical cable to rule out an internal short on one of the speaker cable lengths. If that still doesn't work, you might be stuck with taking the back panels off the rears and checking for internal shorts there; for example, my 9.1s have internal connectors that can loosen and rotate internally, touching and causing a short.

Had a similar problem with my amp and it ended up being a defective HDMI cable.
