It is possible that your system is gettting overloaded and makes the sfety cicuit switch off . This is the protecction circuit to prevent further damage and fire within the system particularity when the output or power is shorted. Check from the speakers for short remove and test . Also use a multimeter to test for short in the output drive. If so disconnect and see if the protect releases. Then you must replace the outputs. Check also the protect cicuit for a false alarrm due to wrong biasing. Hope this advice helps to figure out. Good day
