Recently, while driving my 67, I noticed the radio turned off and then a couple seconds later, came back on. This happened twice a few minutes apart. The next day it happened again, but this time the ignition failed also. I started to coast to the side of the road when everything suddenly came back on. I restarted the engine and drove without problem for a few miles at which time it happened again. This has been happening now for the last 4 days or so. During a typical day of driving, it happens 4 or 5 times. Each time, withing a few seconds everything returns to normal. I suspect the ignition switch and have one on order. In the mean time I disassembled the old ignition switch. It seemed to be okay. It was a little dirty so I cleanded it up and reinstalled it. The problem did not go away or get any better. Does anybody have any ideas what could be causing this. I am going to change the ignition switch as soon as the new one arrives, but if that doesn't fix it, I will be at a loss for ideas. Any suggestions would be greatly appreciated.
