Deeply Rooted
If planted in a container, true you could have a problem with watering. Also, if planted shallow or if not watered deep enough.
Since you said that watering sometimes brings it back and sometimes it doesn't then it's safer to assume that watering isn't the issue. However, it may be if you're not watering deep enough or if the plant is in sandier soils.
