Was driving and the clutch sank to the floor. Couldn't get into gear so I had to pull over. Once I parked my car, the clutch was completely to the floor. Couldn't drive it because the clutch would not get into gear. Waited about 20 mins and it came up 1/4 of the way and was able to get into gear. This only happens in the summer and it happens about once or twice every other week and if it happens while it's parked, the car is inoperable.
