Hey Kappy,
thanks for your help with this.
Looked into the kernal panic and not sure if that's what is happening. There is no "restart screen". And no other options when the computer eventually is re-booted. The computer shuts off without any warning, and when you reboot it behaves as it would if there was an unexpected power outage.
Is there anything in the console that would indicate kernal panic?
the console just before a shut down today looked like this:

Then it happened again only 10 minutes later, this time the the computer logged this before shutdown:

Is there anyway to test the RAM to see if that is the problem before it is replaced?
As I stated in the OP, the computer has already been to Mac Support and they said all was well with the machine, would they have tested the RAM?
thanks again for your help with this.
