When all else fails, go back to a stock rom. There are bad apps out there that cause unusal problems. I installed I Heart Radio a couple of days ago. Everytime i went to start it, my phone rebooted. That is extreme and easy to see. A lot of apps track phone state. And event could be irratically firing when your phone rings. That is why you need to get back to basics and then move forward until the proble returns.
