Hey Mark,
For some reason I didn't get a notification, so sorry for the late reply.
1. This issue is intereting. I assume this only happens when you fill gas? After that initial 10 minutes, then it is fine until you fill up again? I assume there are no engine codes either. I haven't seen this problem before, but the first place I would start would be checking the fuel pump assembly and lines inside the tank (access in the front trunk compartment). There was a tsb about the lines not allowing to fill the tank properly, but maybe there is a connection problem with the fuel pump that is getting distrupted somehow. Have you done the fuel filter recently? You might want to change that as well (pretty easy and is by the coolant tank).
