[QUOTE="Vate, post: 114581, member: 20420"] I know this is an old thread, but a friend of mine just had the same happen to his Spark. As I also have a Spark, I thought I would research this problem. After reading this thread, it occured to me that one of my life's experiences may help explain an answer to this problem. I have a full sized aeroplane that I built and it is powered with a Toyota Lexus V8 that is computer controlled. I spent over 4 months trying to track a problem where the motor would shut down for no reason and not throw up any fault codes. Fortunately I had a pretty primitive back up system that allowed an extended glide to get back to the airfield (in case you were wondering?). I replaced the computer three times... the last time to an after-market type, but still the same problem. Eventually I narrowed the problem to a relay, and on closer inspection found that the problem was in the mounting block to the relay. When you pushed the relay into the block, one of the female connectors clipped into the block would move down inside the block and so just touch the end of the terminal on the relay. Under certain conditions it would then lose contact cutting all power to the ECU shutting it down and as the system was wired in such a way, it also lost power to the memory of the ECU causing no fault codes to be logged. I fixed that problem, and after several years have never had a hint of a problem such as this since. Hence this Spark problem to me sounds very much like a dirty battery contact allowing a loss of power long enough to shut the system down. Has anyone considered this? [/QUOTE]
