Although this could be a problem with the unit that will require repair, you can check some things to see if it's an easy do-it-yourself fix.
It might be caused by a short on one of the speakers (most likely) or one of the components (less likely) or be due to a problem with the power from your house (remote).
First, while the receiver is off I would inspect the wires to all speakers to make sure there is no fraying or no strands are touching each other and causing a short.
If this looks ok, you should probably disconnect everything, insure the volume is set to low and then try powering on to see if it will stay on. If it still powers off, you can check the mains (power surce) as a last resort (move it into another room where you are sure the wall plug is on another circuit and try plugging it in there). If that still fails you have a bad receiver.
If the power stays on with nothing connected, shut it off and reconnect the two front speakers first. Try it again. Then add in components one by one and then speakers. Make sure you aren't connecting things while the unit is powered on and try it each time you connect something new. In this way you'll identify the offending component.
I know it's a hassle, but it may save you from having to spend some money repairing or replacing the unit.

I fear that there's no easy fix. Sounds like the power supply or the board which controls it is bad. If you're not an electronics repair person, it'll need to go to a repair shop.

Generally speaking, an amp attempts to protect 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 'nekkid'. 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.
