Went to lake the other day for a day of fishing and boat ran perfectly normal all day. Went back to the ramp to load up and I beached the boat to back truck down. When I went to start the motor again it started for a half second then sputtered out and died. After this it would not fire at all as if the kill switch had been bumped. Boat has plenty of gas in it and ran perfect all day. I've had zero issues out of my motor in the 5 years I have owned it. Pretty stumped as to what this could be. Any help is appreciated.
