Okay , I appreciate all parties for sharing their input and great ideas and I know inquiring minds want to know 
The "senior" technician came in the next day, and got it running. When I picked it up and paid the bill..the receipt said " Re-Flash PCM to clear flood condition" I don't know exactly what that means, but he said he got the idea from a TSB and I'm kicking myself for not asking him for the TSB number. I suppose it's possible I can still go by and ask him if he's willing to share. Regardless , it's running and working as it should be for now. I admit, my confidence level is medium at best. In the machine tool controls world in which I earn my keep, I deal with flash memory quite often. It's not volatile, and it's not easy to corrupt. In fact, we usually replace a flash module entirely and then reload the data if corruption occurs, because it's usually the fault of the hardware and will reoccur if it's not replaced. Time will tell I'm sure, I'm hopeful and for now, I'm happy. Thanks again for all the input and maybe this can help someone else !

Scroll down the link a bit and it talks about cranking and flooded throttle body

I have seen or rare occasion Fords that flood when very cold out, to clear the flood condition hold the accelerator pedal to the floor while cranking which turn's off the injectors, once it sounds like it wants to start release your foot and it should run. By flash he does not mean to clear the memory, he means to update the PCM software to the newest version which very well might have fixes for the problem you experienced.

Same issue, ive heard one other 6.2 f250 with the issue
2018 6.2L, 41k miles. No issues or complaints before today. Drove about an hour home last night, parked my usual spot,came out this morning,insert key. Engine cranks over at normal speed, truck doesn't start. After several attempts, can smell gas, pulled plug wire and cranked over, have good spark. Had towed to dealer, they are shaking their heads.. have no clue what's wrong. Even tried using other keyfob... nothing works. I quote " you have everything you need to fire, it just won't run " . Have read similar issues on here related to fuel pump, but I have fuel, verified by dealer, as well as spark. Put on your thinking caps boys and girls and help a brother out 😁
