Air handler blower shuts off

Have a carrier heat pump model 38ykc060330. The air handler blower motor will randomly quit running while in heat pump mode and you can hit the cabinet and it starts running again. BUT, while in emergency heat mode it runs fine, blower cycles as it should. ???????

In heat pump mode.... there is a relay running the blower. In AUX heat mode.... the blower is typically controlled by the sequencer. The model number you posted is for the condenser. There should be another one posted on the air handler.
