Driving home from work, my CR-V suddenly lost power going up hill, shut off and the battery light came on. I pulled over, turned it off and it restarted. This happened 3 times within a few miles. The fourth time it happened it would not restart. We let it sit for a couple hours then went back to try again and all it would do is click. My husband tried to jump start it and it acted like it wanted to turn over. Now when I try to start it, it makes a skreeching sound like metal grinding together. It has 198,000 miles on it and has been running just fine. There was no warning at all to this problem. Also, I don't know if it matters but it was raining when all this happened. Any suggestion as to what this might be would be much appreciated.
