I recently installed a older model Pro-Jection 2D kit, second generation I believe. I've got it tuned pretty well, but after driving 5 or 6 miles, the engine will completely shut off. It happens sporadically. When it happens the RPM gauge seems to drop first. Not sure if I'm loosing a tach signal, or if I have a voltage issue. When it dies, the battery seems weak. It will not start right back up, it needs to set for a good 5 minutes, and then it will restart and run fine for a bit. I checked all wiring connections and they're good. Anyone have any ideas? Thanks for the help!
