Used to have same problem with my Nissan some 7-8 years back at the end the issue was of air-intake, there is ventury system and the other is a mold fitted on top of carburator for CNG intake but in some cases the mold starts taking in air .....

OR

There is something which gets loose after a while and takes in air or disturbs your CNG intake

Try draining oil from CNG kit as well ... go to a CNG mechanic and get it done .. takes 5 mins.

IF still the problem persists you need to get a complete kit servicing ... takes about an hour and would cost around 300 and includes removal of oil from cylinder and complete kit dismantling and cleaning (Although the manufacturer of kit strongly discourage it

Best of luck
