sounds like bad contacts in the contactor. bad capacitor. maybe replace the capacitor and ad a hard start kit.

caps good didnt think about the contactactor its a new unit so pads are good. didnt think it was chattering but will check it out i was thinking of putting megometer on compressor possibly the run windings integrity but the contactors a possibillity thanks for the input.

you have a weird one. the only times i have seen what your describing is if contactors are pitted, loose connections.
check compressor terminals, incoming voltage lines, check voltage drop across contactor. is this single phase or 3?
if something else on the circuit is pulling LRA it could cause the compressor to drop out

check compressor terminal connections
had same issues a while back ended up being one of the spade connections was loose causing it to go out on overload
