Default CEL code P0442 question

Monday had my CEL come on, went to O'Reilly's and had them pull it. It came back P0442, Evaporative Emmision Control System Leak. I had them reset it, and today it came back on again. Both times it came on during start up of the vehicle. Neither codes came on while driving. Since Monday I've done some fairly aggressive driving to see if I can get it to come back during/after boost. Can anyone give me some information or insight as to what I need to look at to get this fixed? I'm not wanting to bring it into the dealership. I have a 1500 mile roadtrip tomorrow and want everything running fine. Thank you all for the help.

Right, is that something that I can get and put together myself with only basic tools? Or does it require extensive maitenance?

There's a link to the Haynes manual either on this site or 247mazdas somewhere. I can't remember but I'm certain with a Craftsman 100+ piece tool kit you should be able to do it.
