Unable to flash controller

My system seemed to go in the fritz today. I heard the part fan running full blast. This usually means that the controller has lost connection to the Raspi. I looked at the klipperscreen and it was blank. Tried to reboot but nothing happened. It was like there was no SD card in it. Having some practice with re-doing RatOS v2.1; I flashed a new card and started a new configuration. When it got to the controller setup, it could not connect. It was like it had no klipper running in it. I set it up in DFU mode and it find it then. I tried to flash and it looked like it worked but then after flashing it still could not connect. Believe me I tried several times. Having no luck, I then tried to reflash from command line. Again this seemed to work but after rebooting the controller, it just appears like there is no klipper running on the controller. I also tried to flash with an SD card. This also did not work. I am out of ideas. Attached are the debug files and some screen shots captured during troubleshooting. Any suggestions?
