I've seen this happen when water gets into the cylinder (HG) - but you'd notice that you're losing water and have a bit of clearing smoke on start up.

Have you actually pulled the plug and watched it arc at the electrode? Try it just for grins...

Is the plug actually wet with fuel? Any way it could be something else?
