1997 7.3 stalling Need help!

I just bought a 97 7.3 f350 box truck. Ran great first two days got an oil change and fix tail lights. But the next day while warming it for about 15mins and it stalled and it would not crank for 10 mins, cranked after that but stalled again. Put new fuel filter air filter csp sensor drained fuel tank new winterized diesel in it now it drives for few miles stalls and cranks right back up. Any ideas on what I should do next? Maybe ICP sensor?

"Got" an oil change, as in, you didn't change it yourself? What oil did they use, and did you confirm that it's topped up? Not that I distrust oil change places, but there's a reason they're often called "Iffy Lube".....

Presumably "CSP sensor" is the CPS? What brand?

Randomly replacing sensors can get REAL expensive REAL fast, and may take you backward (replacing good sensor with bad). Before doing anything with the engine control electronics, get it on a device that can scan for codes, do diagnostic tests, and read live data.

CPS sensors from parts stores are junk. Make sure it is Ford or International part only. Did you change the oil or someone else? Almost sounds like the oil level is low. With oil filter these rigs take ~ 14 quarts of diesel rated oil.

I took it in to get the oil changed. They put a little too much oil in actually. And the sensor was from auto zone:\

Unless you have some evidence that the old CPS is bad, re-install it. It's more likely a better one that the one from AutoZtoned.
