Default 92 Fatboy died on me

I wasn't really sure were to post this so I will apologize in advance. I went riding on my bike to KY. From TN. About a 80 mile ride there, anyway bike ran great up there rode around town stopped at and what not. We stopped one last time to stop at a family farm and when we left my bike started spitting and spurting about a 2 miles down the road and lost all power. No lights,blinkers eveything cut off, go back to start it and nothing. Well I check the battery and everything is fine. After a few min. I knock on the battery and now I have power so we try and start it and it will not start but will crank over fine. We check fire on the coil pack and no fire so we thought maybe that was it. I trailer it home put on a new coil pack and put in a new battery in and still nothing, it just cranks over but won't start and the new coil pack gets fire on the first few cranks but after that no fire. If anyone has an idea of what it could be the help would be greatly appreciated. I also thought maybe a fuse some were went bad but i can't for the life of me cant find a fuse box or any fuses at all. Thanks

Sounds as though the Crank Position Sensor may have taken it's last breath.

yea, thats part of the ignition module that sits under the cone cover.
Use the search function on this site, tons of posts addressing your problem.
I used to be real good at Evo and earlier electrics, they were the epitome of simple to work on.
Good luck.

Sounds like a circuit breaker was involved as well as the bike lost all power including lights.

Would not be uncommon to have a rotor cup touching the pickup or a bad sensor/wiring connection and a breaker in need of replacement.
