Your compressor is drawing too much current for some reason & the over-current "Klicit" (an over-current & over temperature circuit-breaker built into the start-run relay area of were the electrical lines enter the compressor on its side. ) is cutting out to prevent it from over heating.
A)the compressor is starting to seize up.
B) the compressor is over heating due to a defective cooling fan or blocked air-flow through the condenser coils ( dust bunny's plugging the fins) OR it may be over heating because of a low charge of freon due to a leak ( a compressor uses the freon to transfer it's motors heat into the air-flow by dumping it (the heat) into the high pressure gas going to the condenser coils this way as well as the metal case of the compressor itself).
C) a defective overtemp/current "Klicit" or start-run relay itself. or a loose electrical connection(s) on the relay itself.
D) it just doesn't like you.
The attached picture is from a Vendo V-110 but you'll see that it has all the basic components to help you identify them on your compressor.
