My Gottlieb Spin-Out just started doing something weird. First 4 balls play perfect. But once ball 5 ejects into the shooter lane - the game dies. All lights remain on in the backglass and on the playfield, but flippers won't work, and nothing will score if you shoot the ball. Pops won't pop. Etc. Once the ball drains, you can start a new game, and again everything is great - until ball 5 loads into the shooter lane. Then dead. Any ideas on what to look for? Thanks in advance.

Thanks for the reply Howard. I will check that out! : )
Probably not until Saturday though as I'm traveling for work.
