Just bought a 2010 Jeep Rubicon, was driving on Interstate, when there was a beep, then it was like there was no power, the engine light, voltage light and the traction light all came on. The engine was still running but just could not accelerate. Pulled off the interstate, turned it off and turned back on and it was fine. Went to visit grandsons, left three hours later and it did it twice on the way home. The engine light would never go off.
