I don't even know how this happens

As some of you have been seeing I have been having some issues with the WRX. I cleaned the extremely dirty crank position sensor last night and reinstalled everything, started it up and let it idle for a few minutes. No problems. This morning I go to head to work and it takes a second to turn over but it works and runs ok. I get to my work and park, the car dies. I have a turbo timer that keeps the car on wih the key removed for a little bit but after key removal it didn't work. All dash lights go off, no power. Try to start it and absolutely nothing happens. Battery is dead? It's four years old or so. Go back out during lunch to see if I kept that battery receipt. The remote unlock works, I stick the key in the ignition, it starts right up like nothing ever happened. WHAT?!

definitly sounds electrical, like a loose or dirty connector. Get a wiring diagram and start with the basics:

ingnition, efi, main, etc. Then work your way around from there.

Have the battery and alternator tested first. A low battery or dying alternator can cause weird stuff to happen.

I only removed a few things so I went back in and tightened up what I could in the parking lot. More fun for me when I get home today, hopefully with my car

This happened to me after I worked on my car and then didn’t get a good connection to the battery when I put it all back together. After I jiggled it a bit and retightened it, I never had the issue again.

Cars are weird.

I’m hoping that’s what it is. I removed the ground side of the battery to tighten the positive on the alternator, then retightened the ground. Didn’t do anything right away but who knows. This did get me to go out and finally buy a multimeter.
