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 '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.

I would say 'something' in the transport is malfunctioning. It could be laser or mechanical but being intermittent may be very hard to pinpoint even for a technician. It may not be what we call 'economically repairable'.

I had an old Techincs SL-P3 in the 80's that did the same thing as yours - very random. I never resolved it.

Is there and pattern, say, xx:xx minutes/seconds into the disc? Since discs are written from the center out to the edge there could be a mechanical bind in the laser tracking mechanism. I doubt the laser itself is defective as they either work or don't (it is a diode after all) and don't self-resurrect.

If the CD is dying you could pick up a stand-alone player and use it instead. That way you still have the rest of the sound system.

buy a universal remote (with it you can control almost every device that has a remote).

No that is not really possible with this system nor would I recommend using it to record. What is it you are trying to record?
Thanks,

This Problem needs an expert Technician: Your problem is due to a missing Voltage around -30 volts that supplies the screen Processor. It could be an open low value resistor or defective switching transistor. Good Luck Toufic Malek

It's time to take it to an electronics tech. Something inside it has died, blowing the fuse. This isn't a do-it-yourself project.
