Question: Who suspended the party that would have maintained power if the treaty was signed in the Russian Soviet Federative Socialist Republic?

Knowledge 1: Dissolution of the Soviet Union
Faced with growing separatism, Gorbachev sought to restructure the Soviet Union into a less centralized state. On August 20, 1991, the Russian SFSR was scheduled to sign a New Union Treaty that would have converted the Soviet Union into a federation of independent republics with a common president, foreign policy and military. It was strongly supported by the Central Asian republics, which needed the economic advantages of a common market to prosper. However, it would have meant some degree of continued Communist Party control over economic and social life. [SEP] Knowledge 2: Russian Soviet Federative Socialist Republic
The Russian SFSR was controlled by the Communist Party of the Soviet Union, until the abortive 1991 August coup, which prompted President Yeltsin to suspend the recently created Communist Party of the Russian Soviet Federative Socialist Republic.

In June 1991, Boris Yeltsin became the first directly elected President in Russian history when he was elected President of the Russian Soviet Federative Socialist Republic, which became the independent Russian Federation in December of that year. During and after the disintegration of the Soviet Union, wide-ranging reforms including privatization and market and trade liberalization were undertaken, including radical changes along the lines of "shock therapy" as recommended by the United States and the International Monetary Fund. All this resulted in a major economic crisis, characterized by a 50% decline in both GDP and industrial output between 1990 and 1995.
