Kawasaki Vulcan 800 cuts out while riding.?

Last summer my Vulcan would cut-out while I was riding. It was not predictable when it would happen. I would be able to coast to the side of the road, turn the key off and then back on and it would fire back up as though nothing happened. I took it to a repair shop, they checked the carb and finally determined it was the fusebox. So, they replaced that and the bike felt goo as new. But then it did it a couple of times after that. Then the weather turned wet and cold and I stopped riding. I live in a small town and I don't trust the local dealer so I'm looking for possible solutions I can attempt to repair myself.
