Radio/tape Cd Player problems of the 2015 Dodge Dart

This happened to me last year around October to December and it is now happening again. I start my car and I will be driving. The car will then stop running while I'm in drive, steering wheel locks up but radio and everything will still be on. It is almost like my car died. I am then stuck wherever the car breaks down on me at and I will try and start my car. It usually take 2 or 3 times before it eventually starts back up. And I only have to turn the key over once and it will keep turning over the engine until I turn the key to turn the vehicle completely off. It also seems as if I have to sit and wait for the car to run for a minute when it does start back up before I can take off again or it will just die on me again while im driving down the road. I have no check engine light on or any other light on until it shutdown on me. Usually its the battery light of check engine light. But as soon as it starts up again they are gone. I keep up to date on my oil changes. I have no clue why it does this. I also recently changed my battery. I also had battery and alternator tested and they were good. Theres times I notice my car idling on its own when I start the car and when I take it out of park it wants to take off on its own. Both of these issues doesn't happen every time or everyday. Its scary when it does happen as I could be going down the interstate when my car randomly wants to shut down on me. It feels unsafe.

Car stops without warning, will not accelerate and dies, no warning indicators beforehand, only popping the battery light after it stops accelerating. Was trying to merge onto the highway at the time. Radio, interior lights, and emergency flashers still worked, engine would not restart. Car had to be towed home for repairs. Problem was not battery related.
