cutting out at 2800 to 3000 rpm

I bought a 95 F 250 powerstroke in September of 2010. The guy I bought if from didn't drive it much ,got it to turn around . He had trans rebuilt a couple years ago but he had only put about 300 miles on it in three years . Since September I put a brake caliber,glow plug relay ,tires and a bunch of other small things . First problem I had was the truck hickupping and the occasional stall so I put a CPS sensor in . But I still had problem with truck stalling, then I noticed fuel on intake ,so I took the fuel filter housing off and water in fuel sensor was leaking , I plugged it and replaced fuel lines , still had fuel leak ,so I changed fuel pump today . No leaks yet ..But when I get down on it I noticed the truck starting to cut out around 2900 or so rpm . Is it the rev limiter or what?
Truck is all stock did the ccv mod today truck gets 17 to 21 mpg.

Brand new fuel pump installed yesterday ,new fuel filter about 200 miles on it .Engine oil has about 3000 miles on it rotela with motorcraft filter .I really don't think the man that had the truck before me took care of maintenance,when I got it the oil was about a gallon low . Rembering back to the first day I owned the truck I was driving it very hard ,then it started to ride very bad like there was a bulge in a tire ,the seats were vibrating really hard ,when I got home to check it out the fuel filter cap was loose and I changed the engine oil ,and Never had that problem again .When it cuts out its very fast choppy . Would the EOT sensor have anything to do with that ? I noticed that I don't have the high idle when cold .What is FPR screen ?

EOT sensor wouldnt have anything to do with it. Some trucks dont have the high idle and others do idk what it is really. Ive got 3 95 PSDs and only one idles up when its cold. the FPR screen is on the side of the fuel bowl. when looking at it from the front of the motor its on the right side. Its the silver box on the side (thats the FPR aka fuel pressure regulator) there is a black cylinder you can unscrew off of it. the screen is in there

I had down loaded a really nice manual for 94 thru 97 powerstrokes. Found link on one of these forums . It explains the engine and sensor operation operations in great detail , that's how I found about the EOT . I wish I'd thought to clean all that up when I had it off . I take a look at it tomorrow. Thanks again

it can be gotten to with the fuel bowl still attached. the EOT sensor is on the back of the hpop reservoir. i dont think it would affect anything like that.

No problem. let us know how it goes
