Depends on the cause. Check the console when your system crashes (or if you are in X, try to provoke it by doing equivalent stuff while not in X). True "spontaneous reboots" are rare, but are usually caused by failing or marginal hardware unable to keep up with the demands places upon it. This would be consistent with it only happening under load. If you're hitting a bug in FreeBSD, you'll probably see a panic on the console when it happens. If so, set up kernel debugging as described in the developers handbook, and proceed from there.
