loss of power/shudder/dies at idle in gear

ok guys i've ran into a problem and i've exhausted all my theories except a couple. i have a 2000 f250 and i just replaced my fuel bowl and fuel pump, my truck ran fine for about a week then all of a sudden my truck started acting like it wasnt getting enough fuel it would lose power and shudder violently. it also willl start pouring black smoke. my rpms will slowly drop no matter how far you keep your foot in it until it dies. it cranks right back up and will smooth out if you rev it up a couple times but less than a mile down the road it does it again. my fuel bowl fills up like it should with no air, my fuel filter is brand new, ive ran lucas through it and there is no water in my fuel. this is my daily driver and i need it fixed because i cant juggle school and work while hitching rides everywhere anyone have any ideas before i start replacing injectors?

It doesn't sound like an injector problem sounds like your getting plenty of fuel it sounds like an problem with your turbo have you checked your waste gate and your exhaust back pressure valve.

You have a problem on the oil side of the injections system. Check your oil level, it sounds to me like you are starving the HPOP of oil. When you crank the engine it fills the HPOP res. because there is not a huge demand for oil when you start cranking. Then the truck starts and the injectors cycle expending all of the oil in the HPOP res. The truck will rev for a few weconds then die because there is no oil to operate the injectors. Either you are low on oil, or for some reason you are not getting oil up the the HPOP res. There is a check valve that is on top of the block behind the front cover. It consists of a seat, a steel ball, a spring and a plug that threads into the block. If this gets gummed up, then the oil flow to the HPOP res. could be compromised. In any case you are having trouble with the high pressure oil system in my opinion.
