Help!!! Loosing Power/Cutting Out!!!

[hoosier golfer]

Ok guys!! I'm not exactly sure what the heck is going on, but when I take off and give her he!! she starts to cut out, miss, someting.. It happens once it get up between 60-80MPH under WOT. My RPM's don't jump around or anything but the truck starts loosing power and missing for a bit. Has anyone else had this problem?? I'm just trying to figure out where to start looking. And yes my fuel filters are NEW.. Thanks For All The Help!!!!!

Adam,
My 2004 6.0 is doing the same thing. Did you ever figure out the problem? If so,
please let me know. vanossforestry@msn.com Thanks!

if you got an oil or fuel guage that might tell something. Is your boost fine?? other than that I dont know.

any other info about the truck??

i had the same problem man and it was one of the things the techs looked at at ford when i got mine studded they told me it was my turbo sticking whether or not thats true i dont know i hope that can narrow it down for you they replaced my turbo no problems here.

any black smoke while its cuts out or misses?

Hey Adam are you straight piped if not I could possibly see it being a dirty turbo? My buddies dodge is starting to miss alittle at wide open throttle and were thinking torque converter that could also be the case mabey?

Thanks for all the post's guys!! Yep, i'm straight piped!!! It doesn't smoke when it's missing, at all. My boost gauge doesn't jump or flutter when it does this either although i have had a lot more turbo flutter (fart) when I let off the go pedal under moderate acceleration. I also thought it could have been a tranny problem but my RPM's don't jump around either.. I'm leaning more towards a leaky EGR Cooler or Low fuel pressure.. What do y'all think.?.?.?.?

I had the same problem not to long ago. My problem ended up being the Check valves in the HPOS. The tech said he replaced the IPC and IPR valves as well.

Sounds like the vanes on your turbo are sticking. Pull the turbo and clean the vanes.

i have same problem, very noticeable with turbo turned off. I think the problem is low hpop pressure. when it does it pressure doesnt go above 2000.
