Have had my 71 Cuda 340 4-speed for 20 years plus and never had this happen before. This Sunday it was a very hot day and was out cruising and all was going well as usual. All of the sudden my radio stopped and so did engine as the car lost all power so I had to pull over to the side of road. Car was dead with nothing happening when tried ignition, no sounds and key just turned. No lights, radio, nothing. Opened hood to look around and battery cables tight. As I was standing around after a few minutes the radio all of the sudden came back on. I got in and car started as usual, lights all worked, etc. Was able to start it and drove great and I took it home as I was afraid it would cut out again and I would be stuck needing a tow. Now parked in garage as afraid to take it out. Any ideas what this might me as to a cause.
Also can anyone recommend a good shop and or mechanic in Southwestern Ontario, Sarnia, London area who is knowledgeable about older cars as I know a lot of the newer ones might not be into older cars in the event I need to get car looked at.
