Loose wiring would have the same effect.
Try shaking the wiring while the engine is running and see if the PSI varies. Or run a wire from the battery to the fuel pump, bypassing the boat's wiring and the OPSS, and see what happens. This will tell if the fuel pump has a problem or if it is something before the fuel pump.
When troubleshooting a electrical device it is important to troubleshoot the device
and the associated electrical circuit.
