Are you trained in HVAC?

Did you have someone who is help you?

What was the sub-cooling measurement?

Is this 22 or 410a?

If not I'd say to call a pro for a check out.

A lot of heat pumps have a lock out feature should pressure go too high or too low. However this feature would likely shut down the entire condensor unit (vs the compressor only). The lockout gets reset by cycling power. You can usually read diagnostic codes on the defrost board.

This unit could also have a bad or marginal cap. Capacitor failures are common even on fairly new units.

Was this a DIY install? If not, then get the contractor out since a new unit should be under warranty.
