I have an 88 lx that shuts down after driving for about 10 minutes. It will restart immediately but stall out again after driving for another 10 minutes. I have replaced everything I can think of including, fuel pump, cap, rotor, plugs, wires, coil, battery, alternator. The issue started after having a radio professionally installed. Any advice on the cause? Any idea on where I can find a complete wire harness? Or a reputable auto electric shop in the Detroit, south eastern Michigan area?
