Was leaving my house just now, heading down the steep gravel road if that matters, and out of nowhere the battery light came on and I lost power steering and brakes. Went down the rest of the hill and now she won’t turn over. It’s trying and has battery but just won’t start. Any idea what could have gone wrong? Everything looks ok in the engine bay from what I can tell, but I also don’t exactly know what to look for. Drove it 40 miles about half an hour ago and felt totally fine. Thanks for any help
