If the low pressure switch is working properly, and the system is properly charged, the compressor might recycle if there is clogging in the expansion control (orifice tube) or if the ambient temperature is low enough to reduce the evaporation rate of the cold liquid.

Pressure switch or wiring or low on 134-A or improper pressure will do it.
Just for a test. If a two wire plugin switch.
Jumper the low pressure switch and wiggle the wiring plugin and see if it will stay running.
But we need a low and high side pressure reading with the compressure running at idle and at 2000 rpm to help.
With one of these.
