thanks for the responses guys, yea, unfortunately I wasn't able to fill up that morning since the gas stations on my way to work are closed at 5:40 am when I leave to go to work. I had initially been ruling out a fuel issue because the engine just died... didn't sputter, or slowly cut out, just flat went off. again on the way home from work it did the same thing, even prior to me getting close to the first gas station. yesterday cleaning the ice out and today checking over all the relays, fuel components, ignition components etc.. I've found nothing wrong, torn, or broken. the jeep has been up and running as normal since chopping out all the ice, filling the fuel tank, adding dry-gas additive, and checking electronics and sensors. I'm going to have to keep an eye on this for sure..... and attribute it to ice buildup on the underside.. most likely a bunch of it hanging on the crankshaft position sensor wire at the bellhousing, causing it to trigger the engine shutdown.

and in my mind I knew my initial question was dumb about fuel lines and fuel systems getting "too cold" because I thought to myself, well vehicles in Alaska and Siberia wouldn't function, but I also thought being so low on fuel and the lines being encased in ice buildup for weeks might have caused a condensation blockage of sorts ... that's why I figured I'd ask you guys .

sometimes you just cant trust your own brain I guess...
