Random reboots iPod touch 3G 3.1.2 and 3.1.1

[csnplt]

I have had my new iPod touch 3G for about 3 weeks, and I love it, but I've experienced random reboots the past couple of days. Most of them occur when I'm using Real Racing. 3.1.2 Restore didn't fix the problems. The screen just goes black, and the iPod touch reboots. Do you think that this is a hardware issue, or a software bug in the OS or real racing?

Anyone else having this problem?

When I play bowling my screen freezes sometimes...but other than that mine hasn't randomly rebooed yet. Hopefully it never will :)

I have experienced the same problem on my 2G iPod Touch since I updated it to firmware 3.1.2. It usually reboots when I play iBlast Moki, in which it has done minimum 3 times in the past 2 days. I have had my iPod Touch for less than a year now.
HELP?!
