It's possible, I had similar symptoms with one of the TiBooks that
turned out to be due to a defective 'logic board'. One good test for
this should be whether it happens in OSX as well.

Did you change that recently? The brutal shutdown probably occurs
because the PMU is unhappy for some reason, so these could be related.
Also, on my last TiBook it happened sometimes when switching CPU
frequency, but I've never seen it with this PowerBook5,8. YMMV.
