496 mag cut out problems

[Dalgo]

I have a 496 mag in a 2007 26' SeaRay Sundeck with 220 hours. The motor cuts out like the key was turned off and on. I had Merc software hooked up while the motor was running and it indicated fuel pump or relays. I replaced both hig and low pressure pumps, filter, and relay which did not resolve the problem. Also. Replaced water impeller, checked voltage connections, etc. all good. The gauges tell me I have high oil pressure up to 92 lbs. I get some fault alarms on the smart gauges when this happens but does not help trouble shoot the problem. Fault alarm shows CAN 1 FAULT. Any ideas or has this happened to anyone else?

CAN = controller area network . check all connections

Have checked all that I can see. Don't know why motor will run fine for a while then start to cut out again
