2005 CADILLAC STS with 60000.0 miles

Car disabled power under load first time 4 yrs ago. Then for the next 4 years continued to come and go. Still happening to this day. Codes: P0651 and P2108. At various speeds and intermittent times would put on check engine light and traction control light. Car cant accelerate. Have to pull over and restart. Biggest mistake was buying an american car.
