Could it be that where you live and where the lamp is located just got
colder? Most fluorescent lamps don't do well when cold. They also often
have problems if they don't have a good ground.
Make sure the ground is good, make sure the lamp is tight in the socket
and that the contacts are clean. Also make sure you have the right kind of
lamp for the fixture.
If it is cold related, you may want to replace what you have with a
fixture that is rated for cold weather use.
