Has happened four times this fall, combine will die suddenly with fault stating “Low fuel rail pressure”. Replaced fuel filters first time bled fuel system and back to normal. One hundred hours later it happened again, did the same thing replaced filters bled system and off we go only this time it only ran for a couple minutes. After the third time we just bled the fuel filters and it was just like we had changed filters there was a tremendous amount of air in system. After the third stall we bled system a second time again and it will only run a few minutes before air enters the system and stalls engine . Where can air be getting in fuel system ?
