Also remove any added Apps to see if one is causing this.
Thanks for the suggestions, and your reply.
Went to the VZW store and couldn't find anyone who knew anything more than to give me a refurb.
Me: "Could it be the battery?"
Them: "It's NOT the battery."
Me: "Is there a way to test it here?" (this store used to keep techies around who could)
Them: "No. Do you want us to order another phone?"
I can try removing the SD card (I asked them if that could be the cause, but they didn't appear to be aware that phones have SD cards). If not, I can try another battery, they're fairly cheap, especially since, as YOU noted, if it doesn't do this when plugged in, it's probably the battery. It in fact doesn't reboot itself when plugged into a wall or car charger.
