My 2008 will occasionally die when I pull the clutch in at low speed if it has only been a few minutes since I started it. That's just one more thing that I've learned to live with.
As for the battery and resetting the clock, it might be time to get a new battery. Yes, you should make sure that you have good connections everywhere, and that the battery stays topped up with a charger, but once it starts doing it regularly, the best solution is to replace the battery. At least that's what it took to totally solve that issue on mine.
