Engine dies

I'm hoping someone has seen this issue before. This truck has the GM engine and shortly after warm up the engine dies. There are no codes in the system, oil pressure and engine temp are good even at the time of failure. We checked harness plugs to be sure they are tight and clean. Fluid levels are good. Not sure where to go from here except changing out the engine controller. I though I'd check here before doing that. Any help would be greatly appreciated.

Yes, we have spark and fuel pressure is good. We're thinking that the ECU is shutting down the injectors.
