I'm no expert Tim, but this is not the "King" for nothing and if it was
easy they would be everywhere and a dime a dozen.

A few of my friends have good luck/skill with this plant and the common
significant factors for them seem to be hard water, pH around 7.6 - 7.8,
rich substrate with lots of organics and some shellgrit, good light but not
direct sunlight and moderate temperatures ( low to mid 70's ) 

Your initial good growth was from the stored energy in the tuber but
unfortunately the growing conditions provided since are not to it's liking
and it will not be able to store further energy in the tuber for the next
resting period.

Hope this helps

Good Luck
