What could be causing this. This has happened 3 times now, and the air conditioner was on each time,I don't know if this is causing the problem. We were driving, we were about 15 minutes away from home, and it started running real bad, and trying to shut down. None of the dash trouble lights came on, not even the battery light. We got off the road, and let it shut down. Tried to start it again, it would not start. It was dead. A guy stopped and gave us a jump. We started back home, and none of the dash stuff was working. No speedometer, no tach, no trouble lights, nothing in the cluster was working. We made it about 5 minutes from home, and it shut down again, and would not restart. Another guy stopped, and gave us another jump, but it would not keep running. I got a ride to my house and got my truck, and went back and I towed it the rest of the way home. I charged the battery, and got it running. It seemed to be running perfect. I checked the alternator, and it was charging 14.00 volts. Now when I start it, all the idot lights light up, and stay on. I put a voltmeter in the car last week so I could see what the volts were doing, and it goes to 18 volts as soon as it is started. If I put the AC Fan and headlights on, it will go down to 14 Volts. When I shut it off, it won't restart until I charge the battery again. Both the alternator and battery test good. I even bought a nother alternator and tried that, still did the same thing.
Sounds Like the Body control module is goin and check your grounds for being Loose and see the could also be in the wiring Harness is a short or the dash panel is shorting out out first by used one then see what happens ther cheap

Last night I checked the battery and it was still good. I disconnected and then reconn ected both terminals and that brought the power back. When I turned the key the power went out again. I repeated the procedure but did not turn the key. Instead, I took off the knee bolster and tried to wiggle the wires under the dash to see if I could find the source since it seems to be related to the ignition. Nothing cut the power so I started it up and it worked fine except for the check engine light which was flashing that says I have a misfire condition. I drove the car 25 miles to work this morning and will be taking it to the dealer for a better inspection.

Battery is probably on it last legs... alternator sounds normal.

You have a parasitic drain problem.
Have any aftermarket components been installed?
D/C the negative battery cable and hook an ammeter between the battery terminal and the cable. Anything over 50 milliamps is too high. If it is over 50 milliamps:
Go to each fuse box and pull 1 fuse at a time, check the change in the amperage reading, then plug it back in. If the reading drops to normal levels (below 50 milliamps) when a certain fuse is pulled, the problem is in the circuit powered by that fuse. Find the different components powered by that fuse and check them.

disconnect the neg batt cable and bridge it with a test light, it should light up and dim after a few seconds, if it stays bright you have a short in one or more circuits, pull each fuse one at a time to see if you can locate which circuit, good luck

not a suburu guy at all, but i'd check the battery it could be its shorted. charge it some more &
see if it will take a full charge 13+ volts & will hold up against a load test.
auto zone & other parts houses will check it for free
