I was travelling at 75 on the interstate when the car suddenly lost power down to 10 miles per hour and wouldn't exceed that speed. i finally was able to get off the interstate. it happened several times again as i was returning to colorado springs. i have a volvo v70xc 2001. i had to have the computer replaced at a cost of almost $1000.the situation was very dangerous.
