Check your volts at the board . It could be to low that it resetting it self
 
Check all the pcbs top middle and bottom +5 power

I found once i had a elevator action where it had a massive voltage drop top was 5 middle 5 and bottom was like 2.5 volts
 
Update:

Reflowed all points on filter board - no change

Any suggestions?

Have eliminated the monitor as I swapped anoth monitor to the game.

Can anyone guide me how to check the M reset or watchdog with a logic probe?
 
Sure, the watchdog is barking?

Try to disable the WD.

Check the contents of the ROMs.
 
Thanks for the suggesting.

I have a successful repair a few minutes ago

I had a bad ram 2016 on cpu board
