Good morning,
in the past I had created a post about this problem this is the link "MCU 'mcu' shutdown: Timer too close.... Random
I was able to download the klipper log without the power going out from the btt relay 1.2 module
klippy.zip (7.9 MB)

Your log shows a constantly increasing amount of bytes_retransmit and also bytes_invalid

bytes_retransmit would indicate some bandwidth problems on the CAN bus.

  1. At what speed do you run your bus
  2. Have you made sure that all devices and interfaces are using the same speed?

bytes_invalid is considered a serious issue on a CAN bus. See CANBUS Troubleshooting - Klipper documentation

Speed for canbus : 1000000
