Thanks for asking your question. I will try and help you out.
Can you get me the engine serial number please? Cat makes a mechanical 3116 and an electronic 3116. Just want to make sure I have the right one.
Thanks for the information.
Is sounds like the engine is loses fuel supply of fuel pressure or sucking air. I have so een this many times.
If you haven't already, I would change the fuel filters. They may be clogged.
If the problem continues. I would next suspect the fuel inlet line may be sucking air. Many times the Chevy has plastic cup lines that get a small hole rubbed into the line and start sucking air.
If the fuel lines are OK. I would next check the turbo for damage or excessive shaft end play and check for a boost leak in the air piping and check for a crack in the air to air cooler. To test for cracks I like to pressurize the cooler and spray with soot water.
If the air system is OK. I must next suspect the governor is worn.
