Not sure if this is the same issue, both myself and the OP both mention it's come from a stop to starting again. I can say in both situations for me, I've been stopped a while, and tried to change lanes - needing a squirt of power and not getting anything.

In fact, my GTI loves coming from a slow down in second, to punching away when a light changes to green. I've never had a car where that didn't feel awesome
