Q: what causes loss of power with high rpms and downshifting during passing attempt on 1999 GMC Suburban 1500

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
when stepping on the gas to pass at 65 mph, the tranny downshifts, the rpms run to 4500-5000, yet there is complete loss of power and acceleration. Also happens when climbing steep inclines. Cat. convertor just replaced.
