2022 Axis A22 - MC-40 Head Unit keeps losing power and rebooting

Found a couple other posts on similar issues, but none like what we are experiencing.

Every 2 to 5 minutes, only when throttle is engaged, our head unit (and all speakers and audio) completely lose power.  The entire stereo system will reboot roughly 30 seconds later, reconnect to bluetooth, and continue playing where the song left off.  When the music restarts the volume indicates it is playing at level 20 (of I think max 45) but it takes 20-30 seconds to get back up to that actual volume level.

Anyone else experience anything similar, if so, any diagnoses or fix?

Thanks.

Malibu sent a replacement MC-40 head unit and dealer swapped out.  No change, head unit keeps rebooting.  Primary amp is now flashing purple and blue for 2-3 minutes before turning solid blue.  Reboot occurs every 1-2 minutes now.

Any update to this? I'm having a similar issue.

Late update.  Replaced the brains of the stereo under warranty and rebooting still occurs but now every 5-10 minutes.  Coincidental change maybe, who knows. Still seems like a short or lose connection somewhere.

With that sort of frequency, putting a volt meter on the power harness would isolate of the issue is voltage or the unit itself, Given that the new unit does the same, it points to an external issue, like voltage.
