Help needed fast! Electric system cuts off no lights nothing

Hi guys im on my motor holiday in germany.
Twice now during driving my bike goes haywire.
The rpm tacmeter goes balistic.
Engine backfires and all electric conk out.
Sometimes it comes back start motor and conks out again.
Open fuse box check fuses and nothing wrong bought new ones just in case.
And after taking fuses out it seemed stable but 50miles out it happened again.
Had difficulty starting any way.
Its stable for now again.
But before i go again tomorrow maybe you guys have ideas.
Im in kind of a pickle.

could it be the regulator craping out when it warms up?

Wouldn't that drain the battery?

yes but after the bike cools down you may be able to restart and it will run until it heats up again

The regulator won't cause the bike to die, even if it's hot. It really sounds like the ignition switch

ALSO check your ground connection, ground strap to frame and engine ground.

If you are on the road, you most likely won't be able to take apart the ignition switch. I suggest rotating the key several times back and forth past the start position and hopefully it will scrape the contacts clean enough to get you through your holiday.

When tapping the fuse box the lights came on and off.
And then stabilized.

The ignition switch does several things. I recommend putting WD-40 in it to try and clean it out. Spray some in, then stick the key in and turn it off and on several times. It could be just worn out. But then there is the fuse box thing, which would be unrelated to the ignition switch. Do you mean the junction box.

I am a motorcyclist, NOT a biker.

The fuse box...also know as the Junction Box is a sealed unit... other than the fuses, there is not much you could check.
Possibly a loose connection to the Junction box....try unplugging and re-inserting the plugs going to it. maybe just a dirty contact.
