The stability control monitors throttle position, steering wheel rotation, vehicle speed, and wheel speed sensors. When it sees a collection of bad info it thinks your losing control. So it tries to help get you back under control through various avenues. It can apply the brakes and it can tell the computer shut off the fuel injectors to reduce power. Your feeling the later one. Now in the event this were and actual event you would notice something odd but you would also notice it helping. In your case you are feeling it working to the extreme because its occurring when not needed. The system monitoring all those things mentioned prior is getting a bad reading. This could be as simple as a bad wheel speed sensor. To diagnose this so its fixed right. A scan tool is needed to see which codes are stored.
