I've got a "newer" 60 in 1 board in an older Jamma cabinet that was working fine, however now when I turn it on the sound works fine but then cuts out after awhile and doesn't come back on unless I turn the game off and on.

Any suggestions on what to look at first?
 
Check your +12 from your power supply when it's out but before you turn it off. If you lose the +12 (or it drops too low), you lose the sound...
