In addition to the passport validity problem Crazydre points out, you're assuming the Consular Agency there can renew your passport in a couple of days, with several of those days being on a weekend. There's no particular reason to believe they can do it so quickly. You'd also need to have passport photos and the other required documents to process your renewal, which can be difficult to arrange while you're on vacation.
The good news is that it may well still be possible to get a passport in time here in the US if you can get to a passport agency. You can call them 24/7 to arrange an appointment, and they can usually handle an emergency renewal if you show proof of upcoming travel. You'll need to bring a completed application form, photos, payment, etc... to the appointment.
