Time for a compressor, accumulator, orifice tube and flush the condenser. You have a restricted o-tube.

Or a faulty evaporator thermister or a faulty pressure swich or a stuck clutch relay causing it to stay on till pressure gets to high and cuts it off as a fail-safe.or get it diagnosed at a shop you trust (I hope you did the last item first!).
