Hi Customer, My name is***** will be glad to try to help Check for restrictions or leaks sucking in air in the fuel lines between the tank and pump. also verify the supply pump is working properly. If okay check the turbo if you are getting heavy black smoke when this happens and low boost pressure. If that is okay look for a hydraulic problem pulling the engine down under to big of a load. Check the hydraulic filter for signs of fine metal/debris indicating a pump or component failure occurring. Let me know.
