Sometimes that can happen if the amp overheats (for protection).

Have you got the amp in a confined space and is ventilation adequate? Check that airflow is ok and that there's no dust clogging vent ports. Does the amp remain powered/cool if you disconnect all the speakers?
 
If i have disconnect the speakers, is the same overheating.
Only if I disconnect the the connector on plate dmb 03 witch they are connecting to amplifire, then is not overheating.
