You can actually use lower octane fuel at high altitude. I doubt that will solve the problem though.
Rangers will automatically adjust the fuel ratio at higher altitude with its sensors. I don't think altitude is sensed but air mass in the intake and O2 sensors on the exhaust keep the air/fuel ratio near optimum. Maybe your MAF sensor is out of range at 9500 ft.
