2007 6.0 starts then stops 5-10 sec later

[PMJJ]

2007 6.0 starts then stops 5-10 sec later, -Good base oil psi -Fuel stays at 60 psi -Batterys good/ cranks fast -FICM stays at 48 vdc -Air tested hi-psi system, no leaks -New IPR valve, CKP/CMP stays sync, -RPM signal above 200, -IPR stays at about 25%, -ICP is about 6-700psi, doesn't lose the ckp/cmp signal, or at least the scan tool doesn't pick it up. Swapped the FICM with a good one.  I am completely stumped, wondering if anyone has any suggestions on anything else to look at. Just seems like I'm missing something basic but all the basic items check out good, just wondering why it won't stay running. 

Any help would be appreciated, thanks alot.

I just put an EGR delete kit in, valve is still in the intake, but no EGR codes.

Does it just abruptly cut out or choke or clack its way to a stall?

Idling normal then just cuts right off like shutting the ignition off or like the the 7.3's did when they lost CKP signal.

What does ficmsync show? Ficmsync is way more sensitive than sync is. If ficmsync drops out then the first thing to check is for a rust jacked cam sensor.

I should've told you guys I had the engine ripped apart, I was trying to run it just checking for oil leaks before I went further.

 I plugged in the MAF, and the MAP sensors and she'll idle all day long. 

Thanks alot for all the help and input suggestions.
