I was driving down the road the other day at 45 mph when my F-150, 5.4L V-8 Triton, died. No warning lights, no out of normal gauges, etc. I immediately put it into neutral and pulled over. Once on the side of the road and stopped I tried to restart - nothing.

The truck is fixed now!!! The problem ended up being a bad PCM relay.

Thank you for sharing the information on the fix.
The PCM relay is located in the fuse box under the hood.
I have attached diagram for anyone who might be looking for this.
