Hey guys I've got an issue that I would like to put past you. I have a rebuilt 2LT 1984. It will drive fine for a few minutes then loses all power then stalls. Can keep the engine alive if I feather the throttle it will keep running but as soon as I stop feathering it stalls. It's time between these occurrences has been shortening from 20mins down it happening every 5 mins. If I let it stall then start it again it will run for a few mins before it happens again does take longer to start then it should (5 second start when hot). The car runs within temps (80/ degrees) turbo runs 8-10psi(3000rpm)

things I have replaced.
-Relays
-Diesel pump(2LT pump. And 2L pump) with turbo and without.
-Turbo run with and with out it on.
-Exhaust
-different oil

Any help on this would be greatly appreciated it's a mates pride and joy.
