Do you have a volt meter to check voltage and an amp meter to check amp draw? Really hard to troubleshoot electrical without?
Sounds like you may have a heating element that is shorting or has a loose connection or a bad sequencer.
The blower and elements are brought on by a sequencer in the air handler.
If the unit starts to blow but after a short time trips breaker , that may be when one of the sequencers is energized
May ether be coincidental or possible utility company may have sent high voltage through a leg, but turning power off and back on should not cause the issue
