1 Suddenly started shutting down after booting up
Replace the logic board & battery a few months ago and have had no problems whatsoever suddenly the computer shut down and then shut down after it starts up. When it’s cold & been off 12 hours I start it up and I can launch some programs but a few minutes later it shuts down. Could it be something as simply as a fan that died?

Sorry for the aggravation Dan

See if you can run the onboard diagnostics. Restart your system and press the D key. Let us know if you get any errors!
Reference: Mac startup key combinations

I was able to run the quick diagnostic and no errors were found - I tried to then run the more thorough diagnostic and it timed out after 31 minutes and shut down

Did you catch the test it was doing when it failed? Still to many suspects!
Was it Professor Plum or Mrs Peacock who hit Colonel Mustard over the head with the crowbar! ;-}
