I'd check the grounds first, that's usually the culprit.

If your bike still has the original type fuse panel (4 position glass fuses), that may very well be your problem area. They were OK 30 years ago, bit they are now worn out. The clips have lost tension. Resistance increases and the voltage drop causes intermittant problems.

Replace with automotive blade type fuse holders. Solder the leads and use heat shrink tubing.

Might have a look at your brushs. There is a wear limit line on them.
Have you checked voltage at the battery?
