Shut off while driving, no spark

So I'm having an issue with my truck fuel injected. I was driving it to work and it just randomly shut off on me. Just shut off. No symptoms before other than had issues starting it would crank then pop off and run like a champ. Now that it has been shut off. I have ran test after tests. Swapping parts. I've changed the ICM, crank sensor, both coils, and all wires. And I tested with new spark plug still no spark as I had my girlfriend crank over the motor. So as far as I can go I've done all ignition systems other than the main brain, the ECM. Check engine lights on and cranks like a champ just no spark. So I'm thinking not the ECM because I'm sending and receiving signal to it. I'm about all out of options. And yes all fuses are good. Need some help please!
