Other Fuel System Tank Filling/charging problems of the 2005 Nissan Pathfinder

My wife and I were out shopping in our 2005 Nissan Pathfinder se. On the way home the SUV just stopped running on a busy intersection. The fuel gauge read at half. After trying to turn over the engine it still wouldnt start. A fellow citizen helped push it to the side of the road. I went home to get the one gallon fuel tank and pured it in the SUV. I hopped in and tried to start it. The SUV started but the engine light came on. The fuel gauge was reading half still. After unloading the truck. I went to the gas station to fill up. I noticed after filling up, the gauge read empty. The engine light and the gauge light was still on.

[fuel level sensor] service engine light went on August 10, 2008, two codes p0463(fuel level sensor) and p0420(catalytic efficiency low). Shortly after this; when filling-up the fuel gauge would read "e" after some time it would read correctly. This problem is intermittent. The service engine light has been on since then and I've had other issues with the vehicle. This Jan. 27,2009 I went to the dealer to fix the cat. , and cancel the service engine light, but the dealer had a hard time link-up with the computer because of some short in the system caused by the rear view mirror(compass). They said the code for the bad cat. Was complete and not the problem, they said the computer came up with a p0507(idle speed control motor). The code p0463 did not come up. As soon as I left the dealer I filled the fuel tank. And now the gauge went to "e" and fuel light is on the dte reads ----, and the service engine light is on (I called the dealer right away and told of the problem). It's been like this for 3-days in a row. I have to bring it back to the dealer.
