I wonder why you haven't checked temperature of CPUs and components before system shut-down! I also know such a behaviour, if some components becomes to hot.......(including PSU!)
Use CPUFanControl to check: https://bigfoot.morphos-team.net/test/PowerMac7FanControl
It's also a good advice to check the system with Apples Diagnostic-CD:
