Hello. It sounds like you may have a sensor issue going on with your car. Most of the time when something like this occurs it is caused by a throttle position sensor that is not working properly. It can also be caused by worn out fuel system or ignition system parts but it is most commonly a sensor. I will usually install my scan tool and drive the vehicle while monitoring what the sensors are doing. This would tell me if there is a sensor issue going on. If the sensors are reading correctly then I inspect the ignition system and also test the fuel pressure. If you are looking to have this loss of power checked, consider having a YourMechanic certified technician come to your home or office to diagnose why it is losing power.
