I'm guessing it's because nothing will communicate with the PCM. I don't have a tune but when this happened to me the dealership was unable to communicate with the computer (until they figured out the ground). I doubt it's your tune.

Yeah that sucks! Unfortunately, I had to have mine towed. But I was at work.....

I've found that the SCT tuners won't upload a tune or return to stock tune unless battery is fully charged. Every time I do mine I have to put charger on truck for a couple hours first. My 2013 F150 was the same so I assume it's the way the SCT tuners are set up.
