Fading gauges , speedo,tacho.

[Tom3k21]

I need help with an unusual problem. The gauges on my motorcycle randomly turn off and on while riding. After disconnecting the motorcycle from the power supply for about an hour, the gauges work for approximately 5 minutes before turning off again. Only disconnecting it from the power supply for a longer period temporarily resolves the issue. I’m out of ideas about what could be causing this.

Thank you for all your suggestions.

That sounds like an internal issue with the internal CPU in the instrument readout.
