No start

Okay so, my car would have a starting problem here and there, the first time I took off the filter on the carburetor and it started. I changed the filter after that, it is a automatic with 12a motor with a holly carburetor, which I think is too much for the 12a, it was I fine day. I changed all four tires that day, on my way to work I was blasting music and hitting it, out of no where all my power turned off for a few seconds and I noticed the engine turned off too. I pulled over and my engine would not turn over. I changed the battery, alternator and starter, still no start. I checked for fuel and compression which was all good. It was also getting a bad idle, when I slow down my car wanted to shut off. So I would put it in neutral so it would not stall. Thanks to anybody that can help me.
