There is Lifepod, a made-for-TV movie from 1993, an science fiction homage to Alfred Hitchcock's Lifeboat. The timing fits, if it was being shown early this century; moreover, if I had to guess when Lifepod was made, based just on the visual appearance, I would say it looks like something from the 1980s.
The plot summary, per Wikipedia:
On Christmas Eve 2168 AD, a ship traveling through space suffers a critical malfunction. Eight guests and crew escape to a lifepod, just before the spaceship explodes, killing all others on board.
The survivors attempt to broadcast a distress signal and wait for rescue. As the days wear on, the lifepod suffers a series of setbacks and malfunctions: air and heat become limited, along with food and potable water. As supplies dwindle, the survivors debate whether, to conserve their supplies, they should prematurely end the life of a critically injured survivor who is consuming a disproportionate amount of supplies.
One morning, the survivors wake up to discover their critically injured crewmate dead. The survivors realize there is a killer hiding among them on the lifepod. Eventually the survivors realize that its possible that one of the people in the Lifepod could have sabotaged the spacecraft, and who wouldn't balk at killing them to keep himself alive.
It does not match in every respect, particularly since all the major characters end up in the Lifepod. However, once they are inside, there is intense competition for resources—to the point that at least one of the passengers is apparently willing to commit murder. The cast includes a mustachioed Rod Silver (who was the director as well as the star) and CCH Pounder.
