This issue is VERY common. Almost everybody who's been around Subarus for a while has seen it before on their car or a friend's car. It's not the rev limiter, it's not launch control. What it IS, is very hard to say, because it seems like everyone who has this problem finds a different solution. For one person it might be the speed sensor, for another a crank/cam position sensor, for another it's a throttle position sensor, etc. It seems like it's always a sensor of some sort, but as far as I can tell there is no way to know which one without arbitrarily swapping them out until the problem disappears.
