Your video sounds like mine did, when my '04 stalled and died on a left hand turn a little while back. Replaced the CPS and have had no issues since. I would highly recommend checking your IPR and ICP as well.
 
Thanks for the reply

Everything checks fine but I haven't been able to duplicate the problem with equipment hooked up maybe I throw three new sensors at it and hope for the best

I just don't want trouble in the rare occasion my wife takes it with the three kids

I wouldn't throw all 3 at it. Mine was intermittent as well; it was the CPS. If it were your IPR or ICP, a scan would show it.
 
Well they are coming up clean I've seen so many 6.0 and have never seen a cps go but I guess there is a first for everything

If I had a $1.00 for every time someone said that, when we were replacing mine... Lol but it's what the issue was. Good luck, I'm curious if it ends up fixing it.
 
What color does it go when it dyes? :D


The issue could be as simple as EBS wire group rubbing on a stud on the driver's side
valve cover. If grounded out by a bounce, the engine will die, and will catch itself once the wire is off the offending stud.
 
It goes yellow lol
I noticed I spelled it wrong but can't go back in to edit my post

Ill check the ebp sensor wiring this morning I got rained out from work so maybe mess with today

Everything had tested out fine on the truck numerous times so I decided to start throwing parts at it and the first one fixed if

I put an icp sensor in it problem solved so far I have a couple hundred miles on it

Problem is back seems to coincide with hot weather any ideas all the vitals look great

Sometime the wires will rub on the icp harness on late 04 cause they're pulled too tight going to the cake cover. Otherwise I would say if you live anywhere that has winter weather that they treat the roads for look at your cam sensor ice seen the block Rudd under the bolt tab for the cmp and it started to break the sensor apart internally causing intermittent running issues that were exacerbated by ambient air temperature

wiggle icp wires while running and listen for a stutter or if it dies. It is common.
 
I'm gonna check all these things today

Thanks guys I posted this on four forums three of them claim to be powerstroke ford and none if them got many answers it seems everyone is trying to help I appreciate it

I will report back

Surging sounds to me like the IPR. Unfortunately you dont always get codes when sensors are failing it can be a little trial and error.
 
Well I pulled the cam sensor and the metal end was loose and was scuffed from bumping the cam so I replaced it and so far so good I do need some more extreme temperatures to verify but it has been in the 80's so I think I may have gotten it


I will post again after some heat or if the problem rears its head again but of it comes back I'm gonna give it an ipr
