I have a superman pinball that when it boots up it is fine for about 30 seconds to a minute and then it is like it reboots. Then it will stay on as long as you have it turned on. It does it every time you turn it on. All caps have been replaced in game power supply etc. Does anyone know what could cause this?

Found the problem. It was the microprocessor chip. It would not function properly until it warmed up a little. I could freeze spray it and the game would shut off until the chip warmed back up. Replaced the chip and now it works great. Just thought i would share my repair incase anyone else has the same problem.
