Egyptian President Anwar Sadat expressed hope yesterday that President Carter's call on Wednesday for new summit talks will avert "stalemate" in the Middle East peace effort.

In Jerusalem, some Israel Cabinet ministers told the Reuter news agency they have urged Prime Minister Menahem Begin to take a more conciliatory stand on Palestinian autonomy in his talks with Carter next month.

The Israelis said they believed time was against them. One was quoted as saying, "The Americans will no doubt apply pressure on Mr. Begin at next month's talks in Washington, but they know they cannot go too far in a presidential election year. They will have no such inhibitions after the November elections."

Sadat, speaking to reporters in Cairo, said the last session of three-sided talks on Palestinian autonomy "materialized to nothing. There's the threat of stalemate and stagnation. So immediately after the talks I wrote a personal letter to Carter and expressed my views."

White House press secretary Jody Powell said Wednesday that separate meetings by Carter with Sadat and Begin would "review the progress and pace of autonomy negotiations for the West Bank and Gaza." He discounted a session of the three together but did not rule it out.

Sadat, in an interview with Israeli newspaper Maariv, was quoted as saying, "Without an agreement between myself and Begin, the ministers participating in the autonomy talks will not achieve significant results."

Egyptian officials said Sadat will leave April 8 for a two-day stay in Washington. Israelis said Begin will go for two days sometime between April 9 and 16.

In another development, Israeli Energy Minister Yitzhak Modai said in Tel Aviv that in talks next week in Washington, he will raise the possiblity of activating a year-old emergency agreement for U.S. supply of oil to Israel. The commitment to a 15-year supply, if needed, was attached to the Israel-Egypt peace treaty negotiated last year.
