Question question on 7.3 running sluggish

I have a 2000 F350 7.3....truck started acting up tuesday night on way home..ses light came on, ran very rough--about 45-50 mph top speed, shifted very hard into gears....took to dealer wed morning---of course they said MONEY,MONEY,MONEY---need 3 injectors, wiring harness and idm module...anyways picked truck up took someplace else...they did buzz test..FINE....checked harness's...FINE....said bad battery pass side...have to admit runs better...ses light not on but still not totally fixed...idle's fine, drives good(up to 75+ mph) BUT when you punch it to floor....ses light comes back on and starts running bad again, kill it, re-start light off and will run fine again until you floor it, either at takeoff or going down road....have changed fuel filter,added injector cleaner from auto part store and friend had extra idm module put that in but did not help and still same thing...changed cps about 1 1/2 month ago...kinda almost like bad diesel or fuel pump-->>Maybe??? sorry for so long but.....any suggestions...????

Have you checked the fuel pressure? It may have a weak fuel pump or blockage in the fuel lines.
