    Ac compressor not staying on
    The unit I am working on has everything new like capacitors, contactors, and even a hardstart and only last about 10 minutes. What else can I do besides replacing it?

    Sounds like you spent big $$ on parts for no value. When the unit was running what were the pressures of the system?

    Need both pressures.
    Check all electrical devices on the unit.

    Make sure the 24 volt control circuit is pulling in the compressor/fan motor contactor for the outside unit.

    Dirty condenser, indoor fan not working, low refrigerant, plugged filter or indoor coil, the list goes on, keep on changing parts, you will get it sooner or later.
