Please help glastron gts 207 2016 turning off

[Ctmadrig]

We have a glastron gts 2016 207 jet boat. We were on the water running a few minutes later it turned off and then does not want to turn back on, no crank or anything the check engine light goes flashing. if I disconnect the battery and leave it about 10 seconds and connect it back the boat turns back on with no problem but will only stay on for another few minutes ( boat has a brand new battery)

Check your relays in the engine fuse panel. These are known to fail. Replaced mine this spring.
