The model number you submitted is not a valid model number. Without having a valid model number of your water heater I will only be able to provide general information. The pilot flame could be blowing out due to a draft, dirty pilot burner, faulty gas control or a faulty thermocouple. If there is not a draft blowing the pilot out, I would replace the thermocouple first.
The pilot flame could be going out because the pilot flame is not engulfing the tip of the thermocouple.
I recommend calling a service technician to diagnose and repair your gas water heater.
