The latest negotiations started Sunday evening following international pressure to install a civilian-led administration, a key demand of thousands of demonstrators who have spent weeks camped outside Khartoum's army headquarters.
Meetings in the early hours of Monday ended without agreement, but the ruling military council announced the talks would resume Monday evening.
A prominent protest leader who was involved in the Sunday night talks said they had revolved around who would lead the new governing body.
"The dispute over the presidency of the sovereign council and participation between the civilian and military still exists," said Satea al-Haj, from the umbrella protest movement the Alliance for Freedom and Change.
The Alliance, which led the nationwide campaign that toppled longtime autocrat Omar al-Bashir
Head of the National Congress Party. He came to power in 1989 when he, as a brigadier in the Sudanese army, led a group of officers in a bloodless military coup that ousted the government of Prime Minister Sadiq al-Mahdi and eventually appointed himself president-for-life. He has fallen out with his Islamic mentor, Hasan al-Turabi, tried to impose shariah on the Christian and animist south, resulting in its secessesion, and attempted to

last month, has been at loggerheads with the military over the makeup of the new body, set to rule Sudan for a three-year transitional period.
"The military council is still insisting that the president of the sovereign council should be from the military," he said. "They are justifying it by saying the country faces security threats."
The protest movement insists that the head of the body should be a civilian and that the council should have a majority of civilian members, a demand backed by major world powers, al-Haj said.

However,

he said Sunday night's talks were "positive" overall, and the ruling military council has said they will resume at 9:00 PM (1900 GMT).
Military council spokesperson Lieutenant General Shamseddine Kabbashi said the "structure of the sovereign authority" had been discussed during the night and that a "final deal" would be agreed later on Monday.
Previous rounds of talks have seen the generals and protest leaders agreed on key issues including a three-year transition period and the creation of a 300-member parliament dominated by politicians from the protesters' umbrella group.
The new governing council is expected to form a transitional civilian government, which would then prepare for the first post-Bashir election following the three-year transitional period.
