My 97 f350 will run fine until it warms up. Then when it idles it will shut off like I turned the key off, but there is no check engine light and if I crank on it it will start after 5 or so cranks. What could this be?

Sticking IPR or bad IPR o-rings. The way to check it would be to hook a computer to it and watch live data and see what the IPR percentage is at idle.
