Multiple Failure messages

I have a 2021 255xe. I am getting multiple failure messages: 1) transducer communication failure, 2) stereo remote communication failure, 3) joystick communication failure. Additionally, neither engine will start. I have checked all the fuses. We had similar failure messages the first year we had the boat and it ended up being the starboard power distribution module back in the engine bay. The big difference then was that we could still start and run the boat, but certain accessories didn’t work. There is a nearly identical power distribution module on the port side in the engine bay and I’m wondering if power for the starter runs through that side. Thoughts or suggestions?
 
Multiple simultaneous communication faults usually point to a shared power or CAN network issue rather than individual failures. Since you’ve seen a PDM cause similar symptoms before, I’d closely inspect both power distribution modules, grounds and voltage stability first.
