Need more info. Year of truck? Any mods done besides EGR delete? Amy way to monitor truck vitals such as FICM voltage, ICP and IPR? Lastly, when does the no start happen most? Start fine cold but not when it's warm?

It's a 2006 6.0 full egr delete 5 inch exhaust bully dog programmer it starts better when it cold but really does not matter I have noticed it don't want to start alittle more about middle of the day when it already when warm and then cools back off some. Could it be loosening oil presure? Or injector going bad? I've run out of guess and this is the first ford Ive ever owned bought I from a dealer and don't know much else may have had more done to it but I'm not sure do know it has studs and new head gasket

I'm gonna say that you most likely have a High Pressure Oil (HPO) leak somewhere.
