Could be a problem caused by a lack of roots, from under-watering, over-watering, critters such as gophers, crowding from to many pseudostems close together, etc. Some varieties tend to be less vigorous when they flower, not keeping their roots and leaves. Planting depth could be an issue. If the plant is not deep enough, there will be less area on the corm to from roots. If you can see the point where the oldest leaves join the pseudostem, it is likely too shallow. Soil texture can also be an issue. High quantity of organics and lack of mineral soil (clays, etc.) can make it easier for roots to pull out of the soil, especially when wet. You need to be a bit holistic and consider all the factors as they interact.

Added: Removing too many pups is another issue to consider in other cases similar to this. Pups are used by the parent plant for addtional anchoring, especially when the parent had fruit hanging.
