Throttle Control Warning Light On problems of the 2011 Dodge Caliber

The contact owns a 2011 Dodge Caliber. The contact stated that the vehicle experienced a complete loss of power while driving approximately 15 mph. The check engine and throttle body control warning indicators illuminated. The contact pulled over and manually restarted the vehicle. The failure recurred after 3 1/2 hours while driving approximately 55 mph. The vehicle was towed to the independent mechanic where the failure could not replicate the failure. The manufacturer was not made aware of the issue. The failure mileage was 60,200. The VIN was not provided.

I have experienced my car suddenly decreasing speed to around 30 mph after the throttle body light comes on. The second time I was on the freeway, the other times were on the street. Once I turn off my car and restart it is fine, unfortunately this is occurring more frequently. I bought my car new, it is only 3 years old, this should not be happening. It only has 56,000 miles and gets serviced on a regular basis. It does not matter what time of day, if the heater is on or off, it just happens.
