Need to ask....
Why my rxv 1067 after 5 minutes play then suddenly auto switch off...on back the same thing happen again...over a year already my amp.
Dont waste your $ on changing the power cord. If it has been functioning for the past one year, likely your power supplies isnt the issue.
I suspected the protection circuitry is the cause. One of the sensors must have sent the wrong signal back to the CPU triggering the shut down to protect the system itself. Another possible cause is the voltage fluctuation, however, if your 5 mins shut down can be repeatedly achieved without given soundtrack, volume gain or time, then the voltage fluctuation shouldnt be the main problem.
As well, did you changed your speakers, speakers cables lately before the Yammie went into shut down mode? Some speakers are very hard to drive which can cause the amplifier to oscillate and shut down. Loose speaker cables or shorting of them will trigger immediate shut down of the amplifier so i doubt it'll be the case.
Do check them all but i think your amp needs a service
