It sounds by your description that when the burner comes on it is either blowing out the pilot or pushing the pilot away from the thermocouple. You should be able to verify this by watching the pilot through the glass window. Unless there is a direct flame against the thermocouple to the point where it is reddish in color then your burner will shut off.
