Why is it that I automatically lose my connection to the headset if I do not use the phone for a while, even if the headset is set to on? Is there something wrong with my BB or is this just a feature?

Now I realize that I keep losing connection to my headset.. What could be causing this?

Any ideas guys?

it may be that your bluetooth goes into snooz mode and its like a hibernate so that it doesnt use battery
maybe it needs charged again

My Motorola H500 goes into standby mode to conserve power after 5 minutes of non-use, but it remains connected. Perhaps check the instructions/manual that came with your headset? Battery as suggested by trigga 15?
