Hey guys, I just installed my new carter p4389 electric fuel pump. I wired it through a 3 prong safety Safety switch. The power for the fuel pump is coming from the P terminal on the safety switch, the I terminal goes to the ignition switch and the S terminal goes to the coil. The boat will start but on run for about 10 seconds then it dies. I'm guessing the the fuel pump is getting power while cranking but not after I stop cranking. I do have an inline fuse going to the fuel pump. It's a 15 amp but the fuel pump calls for a 10 amp. Would that make a difference? please help me figure this out
