Is this an issue from a game that was working and suddenly started to happen or is this a new addition to the arcade?
In either case the voltages and fuses are the very first things to look at and meter.
I am thinking this would be caused by a connector put in wrong/backwards shorting the +5 when the coin switch is triggered. This would cause the power supply to shut down.
Power supply is my first guess and if it is a switcher it is easy to replace. Meter the fuse also or just replace as they are cheep enough.
Maybe just 'smack' it up side da head. sometimes this works and my father called this 'field maintenance'.
I had a game that did this and got worse with time, The connector inside the power supply worked loose from the solder joints. When you wiggled the output block you could see the pins wiggle where they were supposed to be soldered in. This was a peter chow power supply and is now on my test bench for testing pcbs.
Ok, so I haven't had a chance to pull it out and meter it, but kid figured out that if he adds credits with the right coin side it will credit up and work. Adding coins to the left side causes it to reboot? What does that mean?

Just put a piece of black tape over it and maybe disconnect the wires to it, easy fix.
The wires usually put a ground to the pcb to add a credit. I bet the +5 wire, maybe for the light bulb or something else is wired to that. When the switch is triggered it is grounding something it should not. Take the wires off and meter them to see which has the voltage and that will most likely be the wrong wire for that coin slot. If there is a connector check to make certain it is not backwards and verify the pin outs on the pcb.
Post a pic of the coin door wires in question plez.
