Motorola Motoactv :: Having To Re-pair With Droid X2?

I keep losing my pairing with my Droid X2. It still shows, but I can't connect. The MotoActv app won't let me drop it so I have to go into the bluetooth settings to unpair it then back into MotoActv to pair it again. I've had it two days and had to re-pair it three times. I'm not sure when, nor why, it stays connected for several hours then it's not connected and won't connect.

I'm not sure what causes it. I go out of range and return with the phone quite often. I wear the MotoActv as a watch, but the phone mostly stays in a docking cradle on the desk. I use an Timex Ant+ heart rate sensor and SD10-HD bluetooth stereo headphones. I'm not sure if it's connecting to those. The ability to receive text messages and take phone calls through it was a major factor in my purchase of this device. That's what edges out the Garmin and Timex products for me. This feature not working doesn't make it worthless, but it does make it a disappointment.
