Similar to Lifepod 1993, but not it

This film is very similar to Lifepod 1993, but it takes place in a large ship, not a pod.

I can remember three characters... a technical engineer, being the one sabotaging the ship. And also this military cut character (who looks a lot like Kane from Mortal Kombat) and another girl (I think it was long, wavy black hair). The "plot" twist that sends this one apart, at least back in the 1990´s, is that the ending comes to the fact there is only enough food and oxygen for one survivor and no escape pods or cryotubes, only a device that "could" work as a cryotube. For some reason that I cant remember the "Kane" dude chooses to die instead, by taking poison (which had been previously used on other surviving members). But the girl "tricks" him and drugs him instead, then places him in the "cryotube" and she stays awake to await for the rescue team. Of course, they get salvaged, and he is still okay, surprised that she tricked him and saved him. Rings a bell for anyone? Is definitely a B-movie.
