I got my bike running great. i took it around town and didn't have any problems. i took it out for the first ride up to speed. i hit about 70 and it started to bog down. wouldn't keep going. i slowed down and down shifted and it just kept dying. i pulled over and it died. i tried to start it again but it wouldn't fire. i finally killed the battery. i got it trailered home, hooked up the charger and it fired right up. what could it be?

 

It sounds like the common problem with the regulator, it happens it seems to all F3's at some stage. They overheat & the bike only runs on the voltage from the battery, When they cool back down, they work. Eventually though, they will give up the ghost & die.
There has been a fix here with replacing them with one from a GSXR Suzuki (do a search for it on the site). I had mine done with a heavy duty replacement unit.
There can be other problems with the same symptoms (like the alternator) Its worth noting that when & if you get the voltage output checked, the bike should have just done a run as the reg usually only shows up this fault (before it dies altogether) when its hot. Don't make the mistake & think your battery is at fault.
