Game turns on. Start button is lit. Won't start. Ran test mode, single switches. Says T3 Start Button Closed. Opened up the hood to check wires. Suddenly the switch said "open". Closed it down, hit the start button, and the game started. Played for about 5 minutes and the game reset. Now can't get the start button switch to "open". Any suggestions? Don't see any broken wires or anything disconnected.
