Up a break, the Briton conceded the advantage and was broken himself three times as the big-hitting left hander Lopez took command.
Murray also struggled to hold in the fourth, but a gritty effort took him to the third tiebreak of the match, which he won 7-4 to progress after over three and a half hours.
He will next face the winner of a later match between American James Blake and 15th-seeded Canadian Milos Raonic.
"This was the first match I had played in this humidity for a while so it was tough," Murray admitted to reporters after his escape.

Spanish hopes in the absence of the injured Rafael Nadal now rest with consistent Nicolas Almagro, who beat American wildcard Jack Sock in four sets.
Croatian12th seed Marin Cilic beat Japanese 17th seed Kei Nishikori, also in four sets, to earn a last 16 match with unseeded Martin Klizan.
The Slovakian, who accounted for Jo-Wilfried Tsonga in the previous round, beat his doubles partner Jeremy Chardy of France 6-4 6-4 6-4.
