i would check if you have a short somewhere.....but first make sure your battery connections are tight....gauges turning off and on while riding is usually a sign of a loose connection meaning you hit a bump or something and it briefly clips out...did the bike actually turn off??? i dunno....but that seems to be a very odd problem....take out the battery, put it on a trickle and let it charge to full cap....then reconnect making sure the terminal connections are secure and see what happens.... if that works, we''ll have to start diagnosing further, but like they always say, check the obvious first !

Remove and clean the carbs. Also clean the water trap on the petcock, (gas valve), if your bike has a water trap. Remember to balance and sync the carbs after installing.

no1lampmaste mentioned"earthing". Please check your battery to frame ground carefully. And any other grounds visible on the frame.

Check your coil and the cdi, sounds like they may be overheating and shutting down. Also check for possible vapor lock.
