I have a 1993 pickup and randomly the engine will die. For example today I started the truck to warm up while knocking the snow off after 1-2 minutes of running truck dies. I climb in to restart and there's no power to the ignition. After about 15-20 seconds I hear a clicking, then all the lights on the dash come on, truck fires. Approx 30 seconds of running I see the tach, and volt neater zero out then truck dies. This happens to me going down the road as well. Once the truck dies the door was open and door dinger still working, so that tells me there is still power. The heater blower stopped working as well. Repeated these steps mulitpul times until I had to leave and couldn't mess with it any longer. Anyone have any ideas as to wear to start???
