Phone keeps turning off by itself

[kitty]

Hi everyone,

I bot a Treo 650 in February 2006 and things have been relative smooth last a week ago...The phone keeps logging off by itself and I have no idea why it's doing that every few minutes. Sometimes I would even turn it on and immediately it will turn itself off again!!!!

I have not installed any third party applications. I sent an email to Palm and they said I must have some third party applications....they recommended doing a hard reset, which I did, but the problem persists.

Any ideas?
