Earlier this week while fishing my motor wouldn't stay running and I ended up using the trolling motor to get back. It would fire up and die, fire up and die, without continuing to stay running. Previous I noticed that when I started it, it left black soot on the water. After getting back to camp i did find a vacuum hose that was going from the fuel pump enclosure to the throttle body was split. I replaced it but I still have a problem where it wants to die out on me and doesn't have much power. There isn't a code when turning the key on, so I am confused as to what is going on as it seems to run out of gas. I am going to get a fuel pressure gauge but would appreciate any help. It is a 2012 model.
