It sounds as if warm outside air is being drawn back into the room when the unit is not actively cooling. Portable units depend on room air to carry the heat outside, & therefore will not work properly if the room is too airtight. Provide a makeup air passage by leaving the door slightly open, & see if this helps. Use a room thermometer to see if your desired temperature is being reached. Note that if the wind is strong & coming from the wrong direction, it may not be possible to prevent warm air drawback.

Does the thermostat have a mercury bulb in it, if it does you need to level the thermostat.
When you take the cover off, on the sub base there should be a couple of marks or grooves
One on each side of thermostat, you need to take a level and loosen the screws on the sub base
And with the level completely level align those two marks with the level.
If you don’t have a mercury bulb, then your thermostat may need the heat anticipator adjusted, some you can adjust the bi-metal coil, but I haven’t done that, so I couldn‘t tell you how to do it, or you just have a bad thermostat.

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which will eventually happen,if the compressor is tripping the brreaker as I suspect..

Remove the cover on the outside unit that covers the circuit board and contactor and capacitor. Then start the unit and set the thermostat so that the unit cuts off. Then go back to the outside unit and see if the contactor is still pulled in and the unit is running. Next open the breaker and see if the contactor drops out. If it doesn't your contactor could be stuck. Try to free it or replace it. If not the problem could be in the circuit board.
