No Crank No Start

The Other day I was at a stop light and the engine turned off and all the lights came back on if you were getting ready to start the vehicle again, but nothing happens when the key is turned. I have replaced the ignition switch, all fuses and relays checked, and replaced the battery (needed it anyway) and still the same-thing. I have a 2004 5.4L Expedition Eddie Bauer, any thoughts?

Did you try starting it in neutral or just park?

What is the status of the THEFT and CHECK ENGINE lights when the ignition switch is turned from OFF to RUN? Same for odometer display?

Check and see if the PCM connector isn't unplugged or loose.

Insufficient detail provided, but it appears that the PCM and the cluster did not power up together and establish their synchronization within the allotted timing window. Multiple possible causes but a failing PCM Power Relay is one of the more common failures.
