1995 f 350 starting / running problems
I've got a 95 f350 w/ a 460. It won't start up sometimes but cranks at normal speed. Sounds as if getting no fire. Have spark coming from the coil and rotor turns while cranking. It started yesterday morning - I drive a couple of blocks and it died while driving and would not restart. Towed it home and it would not start anymore yesterday. woke up this morning and it started right up thankfully as now I can work on it in the shade of the driveway. The code read that there is no problems. Could the ICM cause it to quit while driving ? I am leaning toward the stator , or maybe both as I don't want to get stranded. Any help would be appreciated- thanks

Did you check the inertia switch to see if it's got the fuel pump shut off? Turn on the key without starting the engine, and see if you hear the fuel pump run for about 2 seconds. If not, start with the inertia switch. Did you hit any significant bumps when you were driving it before? Also check the fuel pump relay. They do die, but mine's got 152K+ on it, and never a problem. (now that I've said that ....) Sometimes, they'll just wiggle loose in the socket. Another thing to check is the TPS. If it fails so that it indicates WOT (wide open throttle) it will shut the injectors off while trying to start. That's a nifty little feature to keep you from starting the truck with it floored and put your pistons in orbit, but also allows you to clear a flooding condition.
If you're getting spark at the coil, the ignition PIP and TFI are both working fine. I won't say that the cap/rotor/wires/plugs are doing the same, because I don't know the condition of those. Put the truck in a dark place, and have someone else crank it. Look for any sparks along the wires, and around the coil, top of the dizzy, etc. If you see spark, it ain't going where it's supposed to. I won't say put your finger where you see the spark, because Ford TFI's HURT when they get you. Just try to focus on the area, or use a laser pen light to pin point it in the dark, then flip the light on to see what's leaking. Obviously, check the cap/rotor for integrity.
