Nissan Titan: suspect fuel pump or out of gas?

Nissan Titan owner: Had something weird happen with my 2009 Titan SE. I got a low fuel warning saying I had 44 miles left.  Drove to work and when I was leaving, the fuel gauge said I had a quarter tank. OK, whatever maybe it was the way the truck was parked. Drove home with no problems. Was driving into work again and the engine cut out.  Pretty sure I ran out of gas.  Fuel gauge said just under a quarter tank.  Put two gallons in it and couldn't get it started. Battery started dying so I tried jumping it and still nothing, but the fuel gauge changed to almost empty and I got a low fuel warning. Makes sense since I put a couple gallons in. Had to tow it home and it fired right up.  Smelled like it was flooded, but now it's running fine. Any thoughts on what is going on?  The weather has gotten pretty cold, but I didn't have issues last year.

Intelligent Tinkering: If you towed it home and it fired right up by being jumped, then the simplest answer is, you ran out of fuel and then ran out of battery charge. It takes some cranking time for fuel to reach the engine after you put some in after running out. If you're unlucky this is all compounded with a bad fuel pump or one starting to go. Time will tell. If it makes you nervous not knowing, put a can of gas in the truck and get one of those L-Ion jumpers or a spare battery and cables and drive around like that until you know for sure.
