Question S420 Loss of power on any incline or grade

I have a 95 S420 which is showing a decrease in power any time I engage a steep incline. I suspecting it maybe the catalytic converter at 85,000 miles. The max speed on flat ground is approximately 85 mph. On a steep incline the auto reduces to approx. 45 mph. Any suggestions.
