I'd guess it was frodocooper being overzealous again. That guy's been problematic since he started as a mod.

Additionally, weird your pod is dropping out. They're all tested for 12 chips and run at 550MHz at V5 or lower for 24 hours before getting sent out. Each one is tested in various ways both before and after that burn-in, meaning it gets plugged in and run for various durations at least four times.

If it refuses to operate right despite a good controller, good power and all that, talk to the seller about warranty replacement. The seller probably can give you startup and testing advice also.
