I turn machine on and sometimes, while playing, the game will shut off by itself. Sometimes it'll reset and sometimes it will stay shut off. When it stays shut off I have to turn machine "off" and back on physically by flipping switch below machine. And even then sometimes machine won't immediately turn back on. When it doesn't turn back on I wait a bit (10-20 mins.) and then it'll turn on.
When the problem first appeared the machine didn't reset/turn off too often (maybe every 20 or 30 plays). Problem seems to have gotten much worse over time. In fact, sometimes I will turn on machine and let it sit for 5 or 10 minutes and then it will just reset, or turn off, for no apparent reason.
Any thoughts and comments on possible problems/fixes would be greatly appreciated.
