Yeah-I agree-sounds to me like you may be gelled up-burned what could get to the injectors and that's it...
If you can't get it inside, filling your fuel filter with 911 may be an option(an a SD you fill the bowl or filter depending on setup.) This will offset how much you have to warm it up too.
Have you gotten fuel in the last 2 months? If not definitely frozen-although even if you have just a little moisture at 0 can shut you down.
I've used a torpedo heater blowing under the truck along with it being plugged in to assist as well. Think I even stuck a 1500 watt heater under the hood and draped blankets over the truck to help warm one up! ;)
It's supposed to warm up some later this week across the country so ultimately if you have patience that may do the trick...but add some type of supplement to the tank at that point anyhow.
Try not to burn up your starter/batteries-it can be very tempting...
