I would say the Fuel Pressure Regulator. My wife's 05 had that same issue. It didn't look like the regulator was bad but sure enough a few months after the issue started the regulator showed signs of leaking externally. Pulled the vacuum line off it while car is running and see if fuel comes out it.
If that part passes the test I would say it's a ignition issue and it's not burning all the fuel so that's where you could get the raw fuel smell until the catalytic converter gets hot and burns it all up.
