After running a few hours on and on, and after being shut down for an hour, the port engine on our 330 with 7.4's shutdown automatically due to loss of oil pressure. Good clean oil, no knocks, engine will restart and pressure comes up to normal on the dash gauge for about 3 seconds, drops to zero and then engine shuts off. Feels electrical to me, maybe a sending unit, sensor, or gauge. Was not able to check much last night. where should I start looking/troubleshooting?
