Engine Performance problem
2003 Kia Sorento 6 cyl Two Wheel Drive Automatic 135000 miles

While driving around town the Sorento does great, but while I am on the interstate travelling 65-70 MPH, It seems to lose power and slow down, and will not accelerate. If I pull over and start up it does fine until reaching those speeds again. What might my problem be?

If it is good, have the catylatic converter checked to make sure it isn't plugging. Also, I am assuming that the check engine light isn't on. If it is, let me know.
