1997 ford f250 7.3 liter power stroke dielse dieing!

As with any no-start or stall problem you will need to figure out if it is a fuel or ignition issue.
The high idle usually means you have a vac leak or a problem with the throttle body or idle air control valve. The control valve is how the computer controls the idle speed.
You'll need to watch the fuel system and spark to see which is being affected when the engine dies.
You might want to hook a test light up to the coil to see if it is loosing voltage for example.

Wow you change everything, TPS was right thing to do and so is the Idle air control,and MAF and EGR, fuel pressure, So it idles high then some one tried to defeat the stall in gear? Even if there is a vacuum leak creating high idle it shouldnt stall in gear, , What color is the transmission fluid? when in gear in drive step on the acelerator pedal to maintain idle to prevent car from stalling. Just enough to maintain let say 1100RPM. Is there a vibration? I mean a torque convertor vibration. Torque convertor stall are common an GM and Nissan,very rare do I ever see it on Ford. I really belive the IAC is not getting power and is just been adjusted manually, cause I know its not the transmission, At idle in gear pull the plug on the idle Air control does it change in idle setting? If it doesnt change in Idle setting the adjustment that was use to control the setting lower the idle to its normal setting. Plug the idle air control in then.The idle air should change the setting. If it doesnt its not getting the signal it should.

Uh, maybe the scanner is right!?

check oil pressure sensor on strokers need a good oil pressure before they wold start and if they lose it , it would turn off the engine

Check the linkage for loose connection.

Check carpet or anything that can keep idle incorrectly.

====
When engine is cold,use 1/2 can of carburetor to clean out the interior.
====
Check your service record for the last catalytic converter replacement

If you has your last smog check report handy then look for the Nox reading. If it's on the high side then your catalytic may need replacement.
====
Take a long drive (high rpm if possible) to clear out the carbon on the cylinder heads.

Ford 2004 6.0, Driving down road seams like when it starts warming up it starts Missing or accelerating,jerking,as long as you keep the acceleration it seems to work as soon as you level it out it starts missing,even dies at stoping sometimes...Changed fuel filter, put fuel additive in tank still missing,HELP

souns like the fuel pump is going bad

check with Ford it may have a rev limitor

something is not reading right,cant see it being the fuel filter more like air flow or evan in extreme cases inlet manifold is loose or has an air leak like brake servo unit.Try a citreon C3 or a VW golf or ford fiesta with low emmisions and excelent fuel economy ,and no speeding tickets

fuel pressure regulator i have seen a couple go bad
