Trying to remember the name of an old PC IF game

Back in the mid-to-late 1980s I had a game on a DOS PC that I can’t for the life of me remember the name of.

I think it was set on a space station or space ship (or some similar sci-fi setting), and you were the only one left alive. I remember that there was some kind of alien monster running around that would kill you if you took too long to make progress or something (which always happened to me because I was probably around 9 years old when I played it).

Does anyone remember a game that fits this description? Thanks.
