Vehicle has started hesitating and jumping forward

My vehicle listed above will run down the road then start hesitating then dragging down in mph or jumping forward then repeating the action. I will sometimes have to pull over and shut down the engine then start it again and it will run fine for a few miles and the problem starts again. Sometimes I can just hit the brakes and then it will stop for a short time and it will happen again. And it was examined yesterday and there were no problems found. But the red symbol like a lightning bolt going down a tube keeps coming up and the yellow engine problem light comes on.
