I imagine ANY audio source would do the same if played loudly enough.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Hi,

Try unplugging the unit for 60 minutes, then plug back in and try it again. This will reset the processor and hopefully the unit will operate normally. Check all the speaker wiring for shorts, make sure they're also not touching the chassis of the receiver, or are not otherwise pinched or frayed. If all looks well, try disconnecting all the speakers and cycle the power off, then on again.
If it powers up, try connecting the speakers one at a time until one of them shuts the receiver down. Check this speaker with a multi-meter and make sure it is reading between 4-8 ohms.
If not, the speaker may be blown and is causing the receiver to see a short and therefore power down.
If the unit shuts down with no speaker load connected, or fails to power up, then it likely has a bad output transistor, or capacitor and is in need of service. I can send you the contact info for a Service Center near you if you'd like.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
