|Chiller (Wes Craven's Chiller) (1985) [Miles Creighton]: Dies (off-screen) of organ failure, ten years before the story begins; he is brought back to life (without a soul) after his cryogenically frozen body is thawed out and operated on. He dies once again after being shot in the chest by his mother (Beatrice Straight) in a meat locker.
Houston: The Legend of Texas (1986) [Jim Bowie]: Killed by Mexican forces during the battle at the Alamo. (I haven't seen this, so I don't know whether his death was depicted on-screen or not.)
Babylon 5: Spider in the Web (1994) [Abel Horn]: Commits suicide by setting off an explosive rather than be captured.
