7.3 wont run right

Hi all
I have a 2001 f550 with 27k miles on it .When it starts up some times
it lops really bad it my stall but if you hit the throttle right away it will straighten right out. It then started to blowing white smoke really bad and missing with no power After running at 65 mph for 15 miles . I changed the cps and the fuel filter and the o rings in the fuel bowl the lope is still their some times But the truck will go longer before it acts up and if you let off the pedel sometimes it will stop acting up and run fine and other times you have to shut it off for 2 minutes then it is fine again for awhile.While it is mising bad i have opened up the fuel drain and fuel pores out and engine keeps runing but missing bad and blowing white smoke shut it off and wait and start it up its fine. thier are no codes in the scanner
Any ideas
