It sounds like something has happened that should have! Usually, the flowers will fade and drop, while the foliage remains until the cold sets in. They will normally die from the tops down.
Has it been overly wet? This sounds like it failed to take into its spot and may have succumbed to an infection.
I would treat the area with a fungicide, and start over next Spring. You can still plant something else in the spot temporarily, but wait until the infection is gone (usually just a few weeks, so it shouldn't be an issue when it comes to Spring) to plant another Asiatic lily.
