2005 f550 running extremely bad

I have a 2005 f550 with a 6.0. The injectors were giving us fits so we replaced all of them along with new standpipe and plugs. It ha been running perfectly for 2-3 months and now, all of the sudden, this morning it wouldnt idle worth a crap. When you try to start it it would just start super slow and then finally catch and spudder and shake like only half the cylinders were firing.
We put it on our genysis scanner and got these codes:
P0611 ficm
P0262
P0270
P0277
P0278
P0280
P0284
P0528

We read that injector codes coupled with the ficm code told us the ficm was bad. We ha suspected this for a whole but this convinced us. So we replaced the ficm half she'll and it did not fix the problem. We have good logic and and vehicle power. Also ficm power never drops below 47. We are at a loss.

Also, upon first start up the blew black smoke pretty heavily.

Also the truck will even out at higher rpms but Jen it drops back to idle it acts like its gonna die. Another word would be loping at idle. It is also MUCH louder than it normally runs.

just had very similar problem , was bad injector sealing rings ,is your upper fuel filter housing full ,or air pressure evident ,when top comes off ,try bubble test if so ,top off upper fuuel filter housing ,turn key on ,does it fill very quickly ,if not suspect fuel pump ,if it does ,remove ficm relay (main relay) and crank engine ,do you see bubbles in the fuel ,if so its compression leaking past sealing rings ,need to remove glow plugs one by one to pinpoint.

But there aren't very many bubbles and they are very small. I almost wonder if what we are seeing is just engine vibration stirring up the diesel. But we replaced the injectors 2-3 months ago and had a cut oring and had a no start situation. We then pulled every oring and checked each one meticulously. I can't see how we'd have one go bad this late in the game especially after its been running so well.
