Sharing CAN 14v with other 14v sources = interference issues ?

I’m chasing an issue where my fury onboard wideband reads nothing over 4000rpm and then turns back on once Revs drop below 4000rpm

 

i just noticed that my CAN 14v to power the egt module and digital dash, is sharing power with the o2 sensor 14v wire

 

Should CAN devices have there own power source and not be shared to stop interference ?
