This just happened to me; short story is your gas tank collapsed.I have the same car w/ 206k miles. Recently very cold in New York (may, or may not have had anything to do with this). Suddenly one day recently, the gas gauge started going crazy, yellow reserve light was on, needle was bouncing all over the place (assume tank was collapsing under vacuum at this point, hampering sender unit). Not knowing if I had gas or not, i filled up. WHOOSH, big vacuum sound when I opened the tank cap. WTF? Filled up w/ only 5 gallons. WTF? Used the car for another day, and then it died on me, on the approach to the tappan Zee bridge! Knowing I had just filled up, never thinking could be out of gas, I had it flat-bedded of the bridge to the dealer. Dealer says "You are out of gas. We put one galloon in, and it runs". WTF? I took the car to a station, and put another 5 gallons in, filled it right up. Tank only holds less than seven gallons now. Diagnosis is that something failed (vent or purge valve), fuel pump pulled a vacuum, tank collapsed, fuel guage creamed. Car runs great, but sputters out of gas at 80 miles! I know it is time to refuel when she stats to sputtering after a hard turn.
