Strang noise...vibration

I have one of the first Domane plus.
17000 trouble free miles but a problem may be developing.
Only ...in sport or turbo ..when I stop pedaling then start back...it seems as if the motor is catching back up. With a vibration through the pedals. This only occurs for maybe half a revolution of the crank. It doesn't seem to be actually slipping. It's doesn't happen all the time. But is happening more frequently.
It never happens in eco or sport.
Any insight?
 
mine kind of acted that way when they spindle bearing was rusting out from it getting wet and staying wet for too long.
