I have a 1997 GTX. Problem is... sometimes the thing just turns off. It could be while running at full speed or idling, could be after 5 minutes of running or 45 minutes. I always have to remove the lanyard and put it back on in order to restart the engine, never have any problem restarting. Any advice? Bought a new lanyard and had it reprogrammed, still have same issue. Should I replace the post? Is there something more serious wrong? Any help would be greatly appreciated!!
