This problem with the wiring (capacitor) or the relay in the car which is causing the problem .

As far as the guage issue it is most likely a problem with the body control module, have a trouble code test run on the BCM to determine the issue, the stalling is caused by the loss of the idle strategy learning when the battery went dead, the best thing to do is the following procedure I use to clear this issue.
Here is the most common cause of surges and stalls (or very low idle) near or at idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Check for a broken 12V+ or broken ground wire in the rubber boot that goes from the drivers door to the hinge pillar. Had this problem on mine and found both wires broken from years of flexing when door opened and closed. Don't try to splice the break, as the wire is too short and is also brittle. Run new (same guage) wire through the boot and splice inside the door and under the left side kick panel.

There is a vacuum leak under the hood somewhere. Check the vacuum at the speed control servo. If there is no vacuum on the line with the engine running, follow the line to find the leak. The vacuum reservoir is mounted under the battery tray. I would look in that area after confirming no vacuum at the servo.

I would check your headlight relay switch that is located in your steering colum
