Any time you shift stuff around things can go bad or cause loose connections. I had a 67 Camaro that showed 1/4 tank when I moved it from our driveway over into the neighbors for storage. When I went to start it a week later it wouldn't start. My friend finally suggested putting some gas in and it fired right up! Sometimes gauges go bad or the sending unit sends the wrong signal. I doubt it's out of gas, but that's the easiest thing to try first. You should probably put the battery on a charger to top it off as well if you've done a lot of cranking.
