Captivate randomly shuts down

[redz]

I have a Captivate, and it will seemingly randomly shut down. This always happens when the phone is not in use (not used long enough for screen to shut off). When I hit the button to light up the screen, I find out it has shut down.

I've tried setting the screen timeout to 30 minutes to see if I could watch it shut down; unfortunately, it didn't shut down. I've had the phone for over a month, but this is a relatively new problem.

It's just done it several times in the past couple hours - good thing I don't use this as an alarm clock. I've seen other forums with many people complaining of the same thing, but there doesn't seem to be a solution. Has anyone here had this problem? What did you do? Thanks.

It seems to be a hardware-software combo that appears and disappears on certain firmwares. That said, this app seems to be pretty foolproof.

if you're rooted, are you by any chance running a setcpu sleep profile? my mom's vibrant wouldn't wake from sleep so the phone would appear off

If this is a stock phone, no root, SetCPU, or the like, I'd look into a warranty replacement.
