P0446
Evaporative Emission Control System Vent Control Circuit Malfunction.

It sounds like you lost the vent to the fuel system. Try this, remove the fuel cap and see if the engine will continue running. It may set an additional leak code on the check engine, but you will know where that came from.

Try it and let me know what you find.
