Once before I worked on a powerbook with similar symptoms, (maybe it was an ibook). But what it turned out to be was a failed cable underneath the keyboard. Intermittent shutdowns, I guess caused by an intermittent open circuit / or closed circuit in that cable.
I don't remember what your particular model looks like, but if you look under the keyboard are there any small ribbon cables or wires that appear to be at a stressed angle, where possibly the copper inside has failed?
