My Case 380 David Brown engine (diesel) slows down and looses power after running for about 5 minutes. I have changed the fuel filters, fuel pump and check the inlet fuel line to the oilfield pump.
I drained the fuel tank and looked inside and it is really clean. Disconnected the fuel line at the fuel pump and blew back and it s free.
When the engine slows down to about 1200 rpms, I can turn it off and let it sit for just a few minutes and start it right up and run again for about 5 minutes and slow down again.
Anyone experience this or any suggestions greatly appreciated.
