Yes, have fuel pressure, power on the coils and injectors at start and run, and I have about 3/4 tank of gas. It was running on Monday just fine. I took the wiring harness off to do some clean up, and today, the engine won't keep running.
I checked the wiring again, and I need to dedicate wires from the BCM:

C1 - Orange, Hot at all times
C1 - Pink, Hot at start or Run
C1 - Brown, Hot at Run
C1 - Black Grounds.

The PCM was flashed by Brendan.

I need to confirm the power wiring. I had the Pink on keyed power rather than power on Run.. That might be my problem. So, we will see tomorrow.
