I searched the archives and didn't come up with a similar question. This started happening recently on my 71 SBC350 bone stock. It will suddenly die. Funny thing it starts right back up with a turn of the key. Off I go. Has happened three times and while the engine is running but not moving, such as a red traffic signal. Has not died on me while the vehicle is moving. Don't think it's fuel related since it fires right up after it happens and then runs great other wise. Any thoughts? Maybe something in the distributor cap or the coil perhaps? Any help is appreciated.
