It may be self priming, but it's not self bleeding! The smallest air bubble in the injection pump will stop the engine running. I take it that you bled each fuel filter when changing them, but did you bleed at the injection pump? This is a crucial step. I have never been able to change the filters, no matter how carefully I bleed them, without having to bleed at the injection pump. A little air always gets through.
