6.0 wont start!!

[897.3alltheway!]

started it yesterday morning, ran fine all the way to work, then i come out and no start, it cranks and fires for about a second then dies

its on a full tank, and is getting fuel, had AAA double check both batteries only to find that is not the problem, so had it towed home and now im stumped, sorry for bad video, this is what it does

was the vehicle hot/warm when you tried starting? if so, have you tried starting cold?
if no difference, first thing you want to do is scan for codes. most times, it will point you in the right direction instead of shooting in the dark
