I have twin 2016 Yamaha 200's with fly by wire. In the last couple months the motors will randomly shut down. I have had it happen idling out of the marina but mostly while running on plane. It does not happen often, probably once every five trips. Luckily it has never happened in rough water so doubt it is a loose connection. It usually happens on both motors at the same time. I am able to start the motors right back up immediately and they run fine. I notice I lose power 1-2 seconds before the motors shut off. Could it be a faulty kill switch? Anybody run into something similar? It is tough to troubleshoot since it is so random.
