Trouble in 2005 PSD 6.0

[2005KingRanch]

I have now had my truck do this 5-6 times without and with a chip, without on day I picked up my baby from the Ford dealer. It is stalling out and going dead after I hit a hard boost and then half to get into the break within seconds of this. and if I do a burnout or boost hard and let off gas, the truck will stall out on me as well. Does anyone know why? or what is causing this? I have been told by Ford, after running their computer on it, that nothing showed up. And have been told by diesel owners it could be the sensor under the truck up near the front? not sure the name of it. please, please any help on this matter. as it is doing it a lot more now with the chip, a Superchip 1805 tuner. I am tired of the truck stalling out and going dead on me from a stand still to getting the gas hard. let me know. thanks

the CPS, cam positioning sensor, is what I was told to change and see if that works. please let me know guys? thanks

The 6.0s do not have a CPS..well, they might but they are not like the ones on the 7.3s. That could have been a problem on a 7.3 but not on yours. Not sure what it is, but maybe someone will be along shortly. Have you checked your oil levels and all of that good stuff?

Im pretty sure the 6.0 has a CPS. Before reading your second post that is what I was gonna suggest. Do you have a check engine light?

[2005KingRanch]

hey thanks. yeah i am sure it has a CPS, coming from one hell of a diesel mechanic told me it does. also, yes on engine light, and no it is not on. not gauge problems. nothing. nothing shows up on computer either. and no codes thrown from my superchip. just the ****dest thing, and making me mad trying to find out why my truck is doing this. thanks for any input.

6.0's do have a CPS but it is not used for the tach signal like it was on a 7.3. The CKP (crankshaft sensor) is used for that on a 6.0. The CPS on a 6.0 is just used for timing adjustments. Sounds to me honestly like a high pressure fuel problem or a low fuel pressure problem possibly. Change your fuel filters first....to be safe....

does the truck ever not want to start when its hot??

[2005KingRanch]

yeah, the truck will start after it's hot oreven been run hard down the track. not a problem starting when hot. if this is what you mean. just when I get into the gas hard and brake quickly it stalls out on me.
