Have you looked through the Console logs to see what they show? Normally there would be something indicate in there. "system.log" is normally a good starting point though you might need to dig through more of them. Of course, it really helps to know about when it rebooted just to make the log searching easier.
If it does it frequently enough you should be able to find why before too long.
