Ok I bought 92 f2 for 500 bucks guy thought it had a blown head gskt. wrong radiator hose clamps were loose, been riding it for about a month no problems.........til now! started bike up and ran fine, shut it off, went back 5 min later to restart and battery didnt have enough juice to start it, bought new battery 2 weeks ago tonight i started it up rode it 1 mile to a friends shut it off, he asked me to move it and it wouldnt start. waited about an hour and it fired right up! rode it back home shut it off, tried to restart, and nothing. Im at a loss.

 

Service Manual has a whole section on checking the electrical:
