Hello CNGBiFuel !
I came around your post in this forum about the problem with the stepper motor on Bi-Fuel systems. I have the exact same problem with my Volvo. The engine cuts off randomly on CNG when the car is hot. It's on 220k kilometres. I went to a guy who is very famous in my country with the understanding and abilities to fix all Volvo Bi-Fuel cars and he changed 3 different stepper motors on my car with no success. He said that the problem maybe in the computer which is responsible for the CNG and he offered me to change all the electronic and the injectors for the CNG. The thing is that I don't want to do that!

I want my car to be as it is from the Factory...
Do you think that my problem is the stepper motor,or there is a possibility to be the CNG computer?
Thanks a lot for your help!
