Salaam to all fellows.
I recently bought a Rocky jeep 1986 2.8 Diesel. I travelled in Hilly areas near Haripur with four people onboard and there was no issue of power loss/pickup. After travelling for few hundred kms, there is a sudden problem of power loss, jerks and even sometimes during normal drive, the engine shuts off. After then, it starts normally the next moment. Then it runs with jerks or sometimes 100% ok. I have owned many diesel vehicles, but never faced such sort of issue...looks to me as a sort of fuel starvation. I want to know from experts as how to start diagnosing this issue, before going for service/repair of injection pump. The engine is perfect without any blow. Help in this regard will be highly appreciated. Regards
