I drive a 2003 manual base mini cooper with 94k miles daily.

I’ve had the car for about 3 months and the only problem was a bad o2 sensor but I’m lazy and cleared the codes until I could change it out and it still ran like normal.

I drove down the street to a corner store, then when I was turning into the parking lot, the car stalled for no reason. Every time I tried to start it up after that, it jumped to 1.5k RPMs, went down to the idling 1k, then dropped to 0 and died. Had to push it back to my house and I have no idea what’s wrong with it. It’s not throwing any codes and the engine’s not even on long enough to know if I have any dash lights on. I changed the sparks 3 months ago and haven’t touched anything else other than oil.

I’m really lost and I have no clue where to start to fix it?
