driving along & boat motor shuts down. Almost like kill switch related. Unable to get it restarted. Happened one and noticed nut securing kill switch to console was loose. Tightened nut and went back out next day. After about 2 hours, the engine shutdown again. Any suggestions where to start?

Still sounds like a kill switch issue to me. I would contact your dealer in the am.

A dealer can quickly tell you if it's throwing a code. If it is the kill switch, it'll show up as a code in the engine's computer.

Work the kill switch back and forth real fast about 10-15 times. If it's got dirty contacts in the switch that may clean them off.
