I doubt that the EBP valve is totally your issue, but you should address it. Warm restart issues frequently are IPR related. Have you looked at the IPR visually to make sure the nut is in place on the back?

The nut is there. I ordered the rebuild kit. It has oil all in the plug

Ok since my truck is down waiting for parts I removed my turbo to replace o rings and clean up oil. Do you guys have any other recommendations for other maintenance I should do?

Have you checked your turbo for play? Interested in a different wheel? Checked your up pipes? Interested in the HPX or FRX mod? Checked your injector torque and UVH's? HPOP lines?
There is a lot that is easier to access with the turbo out of the way!

NOW is the time to do up pipes for sure. I also would look at the passenger side fuel line where it is a known point of failure. Like rikster said, Turbo wheel, maybe rebuild it while out, the kit is $75ish and you will be good for 200K+ miles if you maintain your oil and let it cool before shutting the truck down.

Depends on which route you take on the up pipes. The IH ones will run you about $400 whereas the Dorman branded ones can usually be had for less then $200 (got mine from Amazon). There are plenty people here that run the dormans with no issues, so this is more down to personal choice. Are the IH ones great units? Absolutely, but to me I didn't see the justification for double the price.
The passenger side fuel rail mentioned runs along the head in the valley, there is a clamp that holds it in place. This clamp is known to wear a spot in the hard fuel line over time, so it is wise to first check the fuel line for damage and either replace or reinstall and put something between it and the clamp (piece of rubber, etc). Some people have chosen to leave the clamp off all together and I don't believe I have heard of anyone having issues doing that as yet.

This is what my pedestal looked like coming out of the truck. I guess you can see where my oil leak was
The lil metal piece was just sitting on the pedistal
Do I need a new pedestal?

I'm with HKusp with the IPR being your issue. Troubleshot a very similar issue with a friend recently, and it was his IPR. His would die if he gave it too much throttle, but then restart right away.

You absolutely can, I know guys in much colder climates than Maryland that have and have no issues. The truck will take a little longer to warm up (in theory) at idle. I haven't deleted mine, because I like it, like the noise, and have it set-up in a decel tune to help brake the truck when towing, but if you want to, go right ahead. One less thing to worry about leaking.

You put a little resistor across it so it won't throw a code. Very, very simple and cheap. There are a couple of threads on it in here somewhere with the resistor details. Once you put the resistor across the two wires to simulate it still being plugged in to the EBPV (for fooling the ECM), you get some heat shrink and secure the resistor in there. You could also use that rubberized electrical tape.

OK got everything back together and started the truck. Same problem once warmed up, it must be the IPR electrical connection, so the rebuild didnt work and I have to buy an IPR sensor. Does any one know who has the best prices? Stealership wants $298
