THIS UNIT HAS BAD SOLDER CONNECTIONS ON REGULATOR TRANSISTORS,REMOVE BOTTOM AND YOU WILL SEE THE BAD CONNECTIONS.ALSO BE SURE TO RE-TIGHTEN ALL CHASSIC GRD SCREWS AS THIS WILL ALSO CAUSE THE SAME PROBLEM.

It's probably self-protecting from heat build-up.
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.

You will need to look for Bad capacitors and replaced ,
470uf 35v as suggested. read about polarity issue when installing the new caps. Radio Shack. Installed it.
Thanks for posting Question, You will need to check the power switch, There are capacitors for .12v/1000uf 25v/1000uf...You will need to check it out if it's working.If not replace or re-solder..
Also you will need to check the sound IC, by tamping on the IC chip, if it makes a sound,OK, but if not, needs to be replaced..
You will need to check the Terminal resistors which is about 0.9 ohms, 1ohms , if not working will be replaced too..
