Definitely doesn't sound right.

These truck's were manufactured for pretty much all types of climates/enviroments so you shouldn't be having starting issues.

Yes, 16 below is damn cold, but as others have posted, they're not having similar conditions in temperatures well below yours.

Take it in.

Grub out!

I like this guess best of all. The strong smell of fuel indicates something like this IMO. Ethanol combined fuels can tend to have more moisture attraction, and the water in the fuel system might go unnoticed in less than extremely cold temps. The check engine light should have a captured code which may more than likely be a cylinder misfire...likely from too much fuel. The strong smell of fuel might limit the number of possible suspects. I was also wondering about a frozen blockage in the fuel line system. All the FI engines I've had up to now in my street vehicles have a regulator that diverts excess fuel back to the tank that's not used by the injectors. I wonder what happens if the return line gets blocked by a water/ice chunk?

Trying to look at the whole sequence of events in the OP's case here in a logical sense, I'd think ice somewhere in the system. The truck never did it before this. An extremely cold temp suddenly causes this symptom. Water isn't supposed to be in the truck's system ideally, but frozen water will definitely wreak havoc on the fuel system. Air and spark aren't as affected by cold as fuel delivery and ratio can be. The strong smell of fuel is possibly the biggest tip off. A code reader is the first step.
