Sounds like the altenator is not keeping up and you are running mostly on the battery. I've encountered a similar situation on one of my bikes-same symptoms. The other possibility is shorted cell in the battery that is drawing down the charge system. A heavy current draw would affect the FI/Ignition at low RPMS due to inadequate system voltage.
