FLEX-6400 Shutting Down

My 6400 with onboard antenna tuner shuts down randomly after about 20-30 minutes normal SSB operation. SWR is not the an issue, I'm using tuned antennas with the tuner bringing the SWR down to close to 1:1. Any ideas?

    Download FRStack and see if you are having a low voltage problem. That is what it sounds like to me. Otherwise, I would suggest opening a Help Desk ticket.
