From your description it sounds like the phone has something mechanically intermittant inside of it. This could be a cold solder connection in the circuit board, or on a connector assembly. Call Blackberry support and get a ticket number for this fault.
I would strongly suggest to get the phone exchanged under warranty.

Loose battery? I had this issue, shimmed battery with a bit of business card (or as someone pointed out, tape a bit of electrical tape to battery bottom).
