Could be moisture on the electrics, give the leads, dizzy and coil a spray with WD40 an see if it still happens. Have a good look at the coil to see if there are any cracks too.
I would imagine after a bit of driving, the heat from the engine would dry the electrics out, hence it being fine all day.

Possible coil pack !!

mine does this. its not the leads or dizzy, i strongly suspect its the coil...but i cant be arsed to check it.

easiest way to find out for sure is when its dark, with your engine running, spray a mist of water over the electrics, look for any arching or sparking.
