2004 6.0 sudden missfire and stall

just bought this 04 f250 eclb. this is my third powerstroke but first 6 liter. a few days after i brought it home it started to develop an intermittent missfire. on 2 or 3 cylinders but would come and go never effecting the driveability. changed the oil and fuel filters soon after i bought it. but christmas eve i was driving and suddenly it seems to have lost maybe all but 2 or 3 injectors, the truck would barely idle and did not have enough power to even make it move. i have no idea what to look for. i thought it was little odd for that many injectors would fail at once. ive tested ficm voltage. came back with 48v and 47.5 under cranking. also after pulling the ficm its dated 2009 underneath. also tried unplugging icp sensor and did not seem to affect the running at all. the engine is dated 2004 and also has the icp on the valve cover so im guessing its a later 04. any help or thoughts would be very appreciated

could be a stuck egr valve, among other possibilities. check for codes. first and foremost

if you're just going to shotgun, pull the valve out first. look to see that there isn't any carbon keeping the valve from closing fully on it's seat

did replace both fuel filters the day before this all started happening. but drove 100 miles or so after changing the filters with out problems. but i pulled the cap off of the secondary housing and when i cycle the key i get bubbles in the bowl. so possibly a leak at the primary filter?
