My Droid 2 ran out of power when I was using it. Plugged it into power and restarted it ok. Notified me there were updates available for apps. Started updates. 20 seconds it shutdown on its own. I could not start it. 3 minutes later it restarted on its own. 2 minutes later it shutdown on its own again. I could not start it. It has been hours and it has been charging and won't restart. Suggestions?
