general problems of the 2006 Kia Motor Amanti

3 different times the vehicle was stationary with the engine on and the a/c was on. Then I would put it in drive and after about 1-15 minutes of driving, the car lost power, and when you pressed the accelerator, the engine would not rev, the car kept on slowing to a full stop. Put the transmission in park, let engine run for a few minutes, then the car would drive forward. The first time it did this, June 10 2016, we had to call a tow truck and take it to nalley kia in lithonia, GA. They fixed it, or so we thought. The 2nd time it happened, July 5, 2016, my husband was waiting for my son, while he was parked, he had the a/c running. When he put the car in drive, it drove/moved for 5-6 minutes and lost power while they were driving, pulled it over, waited about 10 minutes, then it drove again. Third time, 9/9/16, we were at the grocery store, I waited in car, with the a/c running, when hubby got into the car, we drove for about 500 feet, the car lost power, waited a few minutes, then drove it for about another 200 feet. Pulled into a parking lot, turned off car for 10-15 minutes, started it and it drove home with no problems. We tested it the next day and ran the car engine, in our driveway, for 20 min without the a/c on, I drove it and had no loss of power. This is scary, there could've of been accidents.

After driving the car slowly lost power, my foot was on the gas, but it would not go any faster. I noticed this problem seems to happen after the car has idled for long periods. Then it gets power back after car has left to set 30 minutes to an hour. This has happened 3 or 4 times this year. On the interstate and city. Leaving me and my family stranded each time. So far this has just happened in the hotter months. Once it sits it doesn't happen again. Making it hard to take any where to get it checked out. The car stereo also is cold natured for some reason. In the winter it likes to change stations or cds until the car has warmed up. I have never heard of this.
