I'm sure you can find several posts addressing this issue. One of the solutions was to run at least one bottle of Fuel System Cleaner in one tank of gas. You may have to gauge your remaining gas by your mileage.

Unlikely to be contamination in so short of time, so I would not expect Techron to help.
Most likely to be wiring/connections or a sensor bad out of the box.
The gauge will go to zero if the PCM senses fuel not transferring from right tank to left tank. Usually a clogged jet pump. Takes quite a few miles if starting from full. What was the fuel level?
Maybe also a sensor float hung up. Don't know.
If it was me, my first step would be to fill it full and see what it does after driving a while.
