I have the same boat and when it was new I would take it to the lake and run it shut it off and it would not start or sometime would not start when we got to lake than haul it home or to the dealer it would start right up not problems. we were getting all kinds of codes that did not make sense they swap around a bunch of electronics not luck Long story short The dealer said were there was a loose ground connection on the motor (something dealing with the computer/electronics would not let it fire) . Boat always cranked but would not start.
