Nakamichi ta-3a turns off completely. Dead no power all of a sudden

Have ta-3a . Worked fine for years.
Now I have sudden loss of power
After listening to music for a little it shuts off completely. No power button light (neither red nor green)
I use remote with this amp. The very first time this happened it switched from green light to orange light ( orange is stand by or dc relay protection mode). I could power it back on with remote. I believe it just turned off

Second and 3rd times it just dies completely.
I can manually turn it back on it will play for a min and turns off completely (no lights at all)

I've read somewhere about 22k resistors that go bad on nakamichi ta-3a

But the symptoms of those is that an amp goes to protection mode.

Could it be those resistors or it's something else
