A friend has that Monte Carlo Gottlieb 80b that's been acting weird lately.
So it enters test modes when we press start.

I realized the reset board wasn't connected, so I connected it.
The machine wouldn't boot (no display, but lights on).
So, I switched it off and disconnect the reset board.
Then the game would work correctly for a while. But not for long

I'm thinking the reset board is faulty..?

The game can operate without the reset board. Leave it unplugged. My guess is the daughter card with the ROM chip is loose. Solder joints break under that board, it's a known issue with the 80b system.
Gently wiggle that little board while the game is on and see if resets or starts freaking out.
A pinsider on here offers an easy fix, it's called the piggy deux board. It bypasses that wretched little daughter board.
That's my best guess.
