Alright so I just had a new engine put in and my power steering belt fell off and got shredded so I was driving with no power steering up to the store to get a new battery cause this ones beat. So I put the battery in and my battery light is on but I think nothing of it. So I continue to drive around the rest of the day(this is the first day I got my car back) and later on that night my srs light comes on and my rpms and speedometer drop to zero and then like a minute later my spark plugs get cut out so I shut it off. Try to start and nothing happens no crank nothing. I waited a bit and tried again and it started. I drove for like 2 minutes and same thing happened. So it starts up but it's like it thinks it's stolen or something and shuts it down. Anybody know what's going on here? Thanks in advance.
