1983 Mercury Marquis, 150,000 miles. The car will cut off for no apparent reason. We installed a new ignition coil. We lose our 12 Volts to our coil every now and then, We lose our ground occasionally. We think the problem is either the ignition switch or the main computer.&Nbsp; Thanks for your help.
