The round was suspended as darkness fell at Trump International Golf Club in Rio Grande, Puerto Rico, with Collins 2-under through five holes, while Streelman was 3-under through seven.
The pair share the lead at minus-12 in the rain-delayed tourney.
Derek Lamely used a furious third-round run to move to 11-under par, jumping into a share of third place with Kris Blanks (seven holes) and Steve Wheatcroft (six holes) -- both of whom were both 2-under for their third rounds.
The round was scheduled to resume at 7 a.m. Monday with the final round to follow immediately thereafter. Officials said players will remain in the same groups, and indicated they expect to wrap the up the fourth round by 4:30 p.m.
