Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

Is it not heating in heat pump mode, emergency heat mode, or both? The default heat mode on the AZ55 is heat pump. Does the fan blow in heat mode? It's difficult to diagnose a heat pump with the information given. Since you say the unit cools, it's not a compressor problem. Possible problems could be reversing valve, thermostat, control board, or switch, if it is in heat pump mode. If it is running in emergency heat mode, problem could be switch, thermostat, control board, or heating element.
To determine if the unit is in HP or emergency heat mode, have a qualified technician check the auxiliary control switches. There are 2 sets of these. The set on the left, switch marked ALL I2R. If it is down, the unit is in HP mode, up is resistance heat. Hope this helps some.

Possible that the thermostat can be fault as it seems to read into the heat developed with a wrong sensing thereby shutting OFF the unit.
The second possibility can be the trip off working due to a HIGH current drain when the heating is ON. Remove panel and make sure that the thermostat connections are tight to the panel board. Also the main plug, the main line to the heaters and the control panels are tight and have no SPARKED junctions and connectors.
Once the connections are reset , plug back the unit to confirm if these were faulty joints. If not check the thermostat.
