I had the same problem with my Wife's 4 cyl Wrangler, it was a bad Cat. The element inside broke loose and would block the exhaust from coming out. It would happen after it was drive for awhile or on hard excelleration. Check the cat. Also did you check the ignition control module? The guy to TT is Axe Man, he helped me out before and seems to know "too much" about Sportages, He's the Sportage Yoda!
