    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.

    Are the speakers the correct ones for your amplifier?
    Ian's explanation sure sounds like the problem to me.
