CPS2 Board STRANGE Auto-Reset- Help!

[Arcade-Projects]

My CPS2 Street FIghter 2X board (or Super Turbo) was on for about 20 minutes or so. Zangief stage, I'm just playing against the CPU. Screen goes black mid-match, audio continues to play. Game loading menu (Street Fighter 2X, Made in Japan, etc...") loads while the Zangief stage audio is still running. Finally once the game reached the loading screen animation (with Ryu throwing Hado), the audio reset as well. Really strange.

Additionally, coin counter was also reset from 7 to 0. I'm running my board on a supergun, and I've seen some weird glitches but never anything like this. Is something on my board going bad?

I've had brief fan issues in the past, but the fan was going strong while this was happening (at least it sure sounded like it, as I could hear it running). Additionally, the battery was replaced just a year ago (which I'm sure isn't the issue, but I'm mentioning that anyway). Anyone seen anything like this before?
