installed a Accel 300+ ignition box on my car and it will start up and idle fine for a few mins then die! Same while driving, it will die then i have to wait a few minutes to start it, but it just keeps dying?? If i just plug the coil back to stock it runs fine. Like the box gets hot and shuts down. Could i just have a bad ignition box? I double checked all the plugs and grounds and there correct.
thanks!
