Had almost exactly the same problem very recently with my ST200. Usually means that the battery is below charge, consequently not being charged by the alternator.
Would suggest replacing the alternator ASAP as if/when your battery runs out of charge, you'll lose the entire car electrics and break down!

It could be the batteries on its way out too.
