This has happened to me a few times. Usually after charging, or while I'm on the Internets.

If I were you, I'd remove the battery for a few minutes, then put it back in and try to turn the phone on. If that doesn't work... I'd do it again... eventually it should work. Mine hung up on the Samsung screen a few times, and then turned off. And then it would get to the Windows Mobile screen and shut down. Eventually it worked.

Since then, I haven't had a problem. I would love to know when the phone randomly shuts off though.
