Kool Aid Dispenser!
I have a 2013 GS and I notices the same thing. I finally decided to read the owners manual it says the power consumption of the grips at low speeds can drain the battery and the grips will turn off to ensure starting capability. It seems on mine that the grips cool down at intervals and if I cycle them on and off they heat back up.
Which is a total load of crap!
