Fujistu VRF II Inverter Compressor getting stopped again and again

Hi,
We have a 10HP fujistu VRF II system. A problem has occured merely after one year of its usage that Compressor starts up for 3-4 seconds and then shuts itself down. When checked with Amp meter to check current drawn by compressor, it takes upto 4-5 Amp before switching off. There is No error shown on the PCB when compressor shuts down and after sometime if we keep the unit started , the same sequence is repeated. Is this a compressor fault or there can be other fault also?
