Mammoth water cooled unit model no g036hha-f copressor will starte run for a minute shut off and will not go back on while evaporater fan still runs?

The unit is tripping on its internal safety switches, low refrigerant pressure safety switch or high refrigerant pressure safety switch. To get the unit to operate, open the main disconnect switch and close it again.

The most likely reasons are:

Unit is low on refrigerant.

The GPM is too low in the cooling mode (no water flow).

The airflow is too low in the heating mode (high head pressure).
