Fuel Level Problem S2
 

Hi.

I have a 2010 RX8. A few months ago, I started having fuel level issues. After filling up the tank and driving for many miles, the gauge slowly drops until it reaches 1/4. After that, I can continue using the fuel, but the fuel level stays stuck at 1/4 (the first time it happened to me on the highway, and the engine simply cut out because I had already used up the fuel even though the dashboard indicated I still had 1/4).

Where can I start checking to find the problem?

Thank you very much in advance.
