Once a mission triggers, it won't trigger again. Main and side missions only trigger once in the game. If a main mission comes available and the time limit has expired, Higgins will complete the mission for you. In order to complete the mission, you will have to go back to a previous game file (if you "saved" certain progresses) so it will trigger again.

ALWAYS save progress in your game that you do not want to lose. Otherwise, you'll end up restarting your game several times or missing out on quite a bit.
