Starting Issues (even after warm)

[schwos]

Good Afternoon,

I have a 01 7.3L Powerstroke Excursion, I have removed all chips and still am having the issue.

I am in the parking lock and attempt to start the rig; after running it for many miles; and it will crank but will not start. If I turn off the rig and back on a couple of times and crank a couple of times I will get her to start.

I can't tell if this is a CPS issues or something else? I don't think it is a fuel deal as I would not get it started at all. After it is running it is fine and acts normally.

Open to suggestions.
