NB Just looking with a voltmeter might not tell you the whole story as it will average out the reading over a certain amount of time.It is sounding like a power supply problem as that would appear to be the common factor. Remember it could be a bad connection in the system so you could have good readings at the battery or main panel. You may have to "dig around" a bit. Good luck!
You might be looking for a negative voltage spike which is very narrow but enough to upset everything.
Or even a positive spike on the negative......
But try with the voltmeter first of all.
If everything checks out OK, then take the above comment into consideration.
