Motorola Droid X2 :: Restarting During Bluetooth Streaming?

I get in my car, where my car stereo has already been paired with my droid X2. The phone and the data both connect most of the time on it's own, sometimes I have to go into teh settings and tell it to connect. The main issue is, I will open an application I use to play audiobooks (Ambling) and start an audio book, which works fine. However, 90% of the time when I turn the screen off the phone will then proceed to restart. It will continue this behaviour until I shut down and power back on the phone, at which point everything works just fine. However as soon as leave my car, go into work or the store or whatever, and come back out to my car the chances are high I'll have to go through it again.
