My car stopped accelerating while driving and turned off after minutes (both battery light and brake warning light were on)

I started my car and it started very fine but I saw the battery light and brake warning light both turned on. I started driving and after 15 minutes my car stopped accelerating and I was driving like around 20km/hr ! after minutes driving started more slowing down and suddenly stopped working and never turned on again (no start/no crank). I could park my car with much difficulty by hand at mid night.

What would be the problem?
I have Nissan altima 2004, 2.5S
Thanks
