You may have a runaway application…check your system profiler for any app that is just sitting there taking up a lot of cpu cycles.
Also, you mentioned safe boot allowed a startup, you may want to run disk utility to check your drive and also consider what you might have installed most recently as there could be a software conflict. Try starting up from the Tiger DVD to understand if that reproduces the issue. If it doesm you may want to reset the PMU — do a google search for pmu (power management unit). Search google 'pmu powerbook site:support.apple.com' I am not entirely sure about the Pismo, but most macs have sensors that will deliberately shutdown the mac if it gets too hot. You may want to call AppleCare even if you are outside warranty so that you can report the issue. Consider also, removing all external hardware while you test and ask yourself if you installed RAM recently and remove it if that was done. You should bring your mac down to a minimum configuration both hardware and software wise to rule out those two before considering your mac defective.
