Buderus GB142 Boiler - Power shuts off during operation

Hello all,
I have a Buderus GB142 24/30 wall hung boiler (LP) that is having an unexplained failure. It will power up then completely shut down. Nothing on the display. Turning ON and OFF the rocker switch will occasionally see a flicker, but doesn't stay on. Confirmed have 115V coming into the boiler. I also confirmed that I have 115V coming into the right side of the blue and red wires of the rocker switch wiring harness. I put jumper wires in to rule out the switch, but there is the same problem - no power. If power does come on, it only occurs for a few seconds to a few minutes.

No codes are displayed when the power does come back on, it is acting normal start up. Again, it rarely starts up, but when it does, power only remains on for a few seconds to a few minutes.

Any advice or experience will be appreciated. No heat or hot water in New Hampshire in December is trouble.

Thanks
