The most likely reason it shut off is because the pressure switch sensed too high or too low of a/c pressure in the system and turn the compressor off so there is no damaged done. The first thing you need to do is have the system checked to see if the proper amount of charge is in the system if there is then you dealing with a blockage/pressure issue.
