Just on the way to work today, my 60 just shut off. I still had power but the starter would not catch. Wait about 30-60 second and would start as normal and run as normal. Then about 3-5 minutes later same thing. It would even do going down the road, would not catch if I downshifted. Then would catch and run fine. I have a hellroaring kit that has been installed for over two years with no problem. Could it be coil? Any ideas would be helpfull and appreciated.
