2000 2stroke merc 150 efi shutting down

[sheltonoil]

Hello everyone. Couldn't find a post with my exact symptoms. Engine starts and idles fine, about 3 mins later on water at medium throttle it completely shut down for a 1 sec then kicked back on like nothing happened. A few mins later, shuts down again (like a kill switch) to complete stop. Restarts immediately, and is fine until shutting down again one min later and stays that way. Won't turn over this time, not even a click, but has power to radio, trim, etc. Note that there is no rpm surge at any point, and it's smooth until it dies. Waited 5 mins, started up and gets back to dock fine on low throttle. Didn't try any faster. Doesn't feel hot, oil level is fine and cap on tight. Fuel line bulb is full. Fuel line from tank to motor has been replaced, but not internal fuel lines. 2 batteries, kept on trickle charger. Voltmeter needle broke off years ago. Tach seems to read high but doesn't fluctuate. Help?

Check ignition switch (jiggle it while engine running), lanyard kill switch if any. All other electrical connections. Report back

You should have the blade style fuses...check holders real good as the terminal in bottom loose connections.

Is it putting out a charge voltage ?
