Suzuki DF 90 electrical problem

[Valiant Knight]

Last weekend, I had some unexpected electrical problems with my DF 90 Suzuki (2006).
The engine ran smoothly for a few hours but, when I stopped it and a few minutes later tried to restart it, nothing happened. The battery was ok since the tilt could move the engine up and down, but, there was no reaction when I turned the key: no lights in the rpm meter, no buzzer sound, nothing at all.
After a few movements of the control lever (forward, backward, clutch), removal and insertion of the kill switch and a few retries on turning the key, the lights in the rpm meter finally lit and the usual buzzer sounded. The engine started normally and ran smoothly. The next time I stopped the engine, it restarted normally.
A similar situation happened 4 or 5 times during that day and the following 2 days and there was even one situation where the engine stopped suddenly while cruising at 4000 rpm.
Any hints about what may be causing this?

Thanks

1) The in-gear start protection is staying on even though its in neutral. (mostly likely)
2) Bad ignition switch.

Had a similar problem myself with another boat.

The gear selector may think the engine is in gear and hence cuts the electrics, mine was a tired switch that kept sticking, shouldn't be too bad to replace.

Changed my switch and never did it again

And/or

Check all the connections to the ignition switch, look for the green colouring on the wiring,

Had a similar experience myself last weekend, try the battery contacts, strop , clean & refit with Vaseline on to prevent further problems.
Worked a treat, just a bad contact. Hope yours is as simple
