Typically this is a sign of a dead or dieing battery. When lithium chemistry batteries get old, their voltage will drop off very quickly under a load (where as normally they will hold a very steady voltage even under maximum rated loads). So when you turn your phone on, the voltage begins to drop quicker than normal and this causes an unexpected shut off.

We sell the 3GS battery and have our handy guide to help you complete the swap. Hope this helps and let us know how it goes!
