Their is a recall notice going out for 2011-2014 F250-F550 6.7's. You can look up your vin on the Ford site now and see it. Recall #14E03. I think it has to do with emission's.
I do not know the details. But the complaints were due to quick shutdowns before you had time to pull safely off the highway. So I would guess the reprogram will provide more time to find a suitable place to stop before the engine shuts down.
