: the contact stated the vehicle intermittently lost power while driving at speeds above 40mph. The vehicle resumed power after brought to a stop. The only warning indicator is the tcs light flashing during the reduction of speed. The vehicle was taken to a service dealer two months ago and the dealer replaced the fuel pump, filter and lines. The problem became worse and the vehicle was returned to the dealer who recommended getting a wheel alignment and tire rotation. This was completed at an independent repair shop, but the problem continues. The vehicle has not been returned to the dealer for further inspection.
