The vehicle was in motion about 45 miles an hr when it began to suddenly lose speed once it stopped I was able to coast it to the light. I cut the car off an it started back up. I didn't understand why it did that so I proceeded to find a near gas station. . It started to run again and I proceeded to go home when it did it again (lost speed while the engine was running) still don't know what the problem is had the alternator and battery checked and both are fine. . This was very dangerous!.
