No power no lights on dashboard when I turn the key

[YHB]

I have a 2007 honda silverwing 600.

I am having issues with it starting but only sometimes. Normally in the mornings when it's cold I turn the key and start the bike fine it runs fine starts and stops multiple times no issue but after a while I'm guessing when it gets hot it completely dies on me and dosnt start at all no lights on dashboard as if no power. But then when I come back to it the next day it starts fine again. The battery is good checked with multimeter and tried an alternative battery also my charger was working even with no display on dashboard. Checked all fuses including main fuse in relay. Replaced the relay and still having the same issue. Does anyone have any advice. I was told it could be a fualty ECU or maybe a fualty ignition coil but I don't want to just keep replacing parts that don't need replacing.

Hello and welcome.

Up to recently I had a 600 silverwing for 4 years. I had all the lights go out on me one night on an unlit road which was fun.

Although my symptons were different, engine still ran, no lights or dash, might be worth checking this.

The 12v feed wire from the battery under the LH side panel had totally rotted through.
