Such a shame this keeps going on, but I imagine it will never be fixed until they redesign the starting system.
Before you replace the starter, you might check the starter relay. Mine went bad on my 2010 and would just click. It appeared to be good when subjected to a tester, but was in fact bad. Try the old touching the jumper cable directly to the starter. You only have to touch it not actually clip it on...if it turns over then i'd look at that starter relay. If you don't like sparks, then make a friend do it.
6 hours isn't much, but who knows why these things go bad. I had one suddenly go out on my old KTM too.
