Power loss on 1993 Infiniti J30

This past weekend, I lost power to the car. The thermometer reached near the redline, the battery light came on, the brake light came on, and the car eventually lost all power and quit working. I had the car jumped, it started and ran for just over a mile before all these symptoms came up again. I took the battery in, discovering it had very low cold cranking amps. I replaced it, and the car ran fine. This morning, the car lasted for about 10 miles, and all those symptoms appeared again. The battery light is on, the brake liight is on, and the car has a loss in power. Any ideas as to what I may need to do? Also, I have no heat. That stopped working as well.
