good luck, some one here will chime in...
maybe try unplugging the icp sensor when its not starting? that will set the default setting if the sensor is going?
cps(cam sensor) ever been changed

Sounds like you might have some leaking injector O-Rings. When the engine gets hot the oil thins out and leaks more causing you to loose your injection control pressure. This is only one of many possibilities.

Snowing out. Started truck (99 7.3 F250). idled for 30 seconds and moved it forward in the driveway about 20 feet. Placed it in nuetral and let it idle. Within 10 seconds, it shut off by itself. Attempted to restart, but it only spun over, no fire. I let it sit for a couple of minutes, and retried. same result, but noticed that "wait to start" light was not on. retrieved code reader and hooked up, but it would not link. Checked fuses and found #30 was blown. Replaced fuse and turned on key. "Wait to Start" light came on, but blew again in a second. My thought is that the PCM is bad, but could something else have caused it to fail? I would prefer not blowing another if something downstream is causing the PCM to fail. Thoughts anyone? Thanks, BarryC in Tennessee

try unplugging the fuel bowl heater and replacing the fuse again. Alot of people are having this problem recently.
