My vehicle intermittently turns off while driving. this occurs at a variety of speeds. The engine quits as if you turned off the key, but only for a second or two. Sometimes the engine will restart if speed is sufficient and the transmission remains in gear (Automatic). Most of the time, I am required to put the transmission in Neutral (While continuing to roll down the road), crank the engine, put back into Drive and continue. The vehicle always re-cranks intermittently. The dash lights react as if the ignition was turned off, example - all the lights come on then go off when the system initializes such as the ABS light and Air Bag light. Battery and alternator and connections have been checked. The problem may occur once a week or 3 times in one day. This problem may not occur for 3 to 4 weeks.

Most likely your ignition switch is faulty and needs to be replaced.
