02 7.3 powerstroke wont start when hot!!! help

I bought the truck about 4 months ago and I absolutely love it but over the last few weeks is has been acting funny at times, it doesn't do it all the time but it has been getting progressively worse, ill drive the truck all day and no problems when I shut it off and go to start it again it just cranks but won't fire,
*Batteries are charged and in good condition, oil is a little dirty but full, I have no codes or check engine light on, and my wait to start light seems to be working fine!
*If i supply a fuel source(starting fluid) the truck will fire but not stay running
*And let it sit for 15 to 45 minutes fires right up like there was never an issue.
*there are no blown fuses

HELP PLEASE thanksł

Welcome to FTE. Please be careful with starting fluid on a diesel motor. When you turn the key on and the glow plugs heat up, it can ignite the fluid and damage the motor.

I'd suggest you change the oil with some properly rated diesel oil and see what difference that makes. The fuel injectors fire off of engine oil and dirty or worn oil can affect how the injectors work (or don't).

Often times what you're describing is an issue with the IPR. You can either try to clean the IPR and change the o-rings or buy a new one. Since that can get expensive as a guess, do you know anyone with a scanner that can possibly monitor live data when this happens?

Next time you get a no start, try unplugging the ICP sensor since it will sometimes unstick a stuck IPR. The ICP is on the front inboard side of the driver head.
