Need help with my 01 7.3

hi guys
so i bought a truck from a guy that said every thing was good n found out that it looses power after 5min of driving .
starts fine n ides good for hours but when driving it looses power n starts to smoke n barely moves n starts knocking hard .
was told by that guy that it needs a fuel pick up replaced n i did n also cleaned the tank and blew the lines ,put new filter but same thing.
took it to a guy called diesel mechanic n he said all injectors n harness r good but made me replace the turbo coz the other one was bad n still same thing happens (u hold the rpm to 3k n it comes down after few min n truck gets messed-up)
bought the damn thing n didnt drive yet n really need help getting it fixed .
it's a 200n one ford f550 7.3 that cannot pu it self
thanks a lot

sounds like the coil in the IPR valve is getting weak when warm and not holding pressure. need a scan tool to monitor these.
