Had the same problem - could be either the gas tank cap is not tight, and not sealing airtight, or it could be a bad oxygen sensor in the engine, causing the air/fuel mixture to be off. Went through this with my '98 too. I had the O2 sensors replaced to pass emissions and it came back on.. I probably have a problem with my intake valve, running too lean and tripping that sensor.
