Compressor works fine at start up and then quits after 4-5 minutes and then will not start up again until everything cools down somewhat. It is fully charged and everything looks good. Pressures are normal while it is running and when it is stopped.

Hello,

I would suggest to first carry out a CAN scan to check if any climate control faults might be stored.

Here's how to carry out a CAN scan:

General Air-conditioning failures.

If no codes are set then next I would suggest to use a suitable diagnostic tool and look at live data for the pressure switch and evaporator temperature sensor.
If the reading for the pressure switch goes above or below a certain set point the compressor will be deactivated. Same if the temperature for the evaporator goes below 2 degrees C, 3.6 degrees F, the compressor will be deactivated to prevent freezing/icing up.

Also check the ambient temperature reading, the compressor is not activated at temperatures below 5 degrees C, 9 degrees F.

Please let us know how you get along.

Cheers, Boris
