Have you always used the same set of batteries?
NiMH batteries have a limited lifespan, ie. they can only be charged a
certain number of times before displaying just the symptoms you are
describing.
I think the fact you mention it works properly on alkaline batteries
tells you all you need to know - your NiMH rechargeables are life-
expired.
