Engine shuts off at idle?

It’s long but any help/advice is greatly appreciated. So, two months back I was driving, and my engine just shut off while at a fast-food drive thru but turned back on immediately. A couple of days later I drove it to the store and just shut off again, I went inside and after 30 minutes came back out and it would not start. I stopped driving and it sat until the computer was replaced and for about a week it ran fine until on my way home it just shut off while I was driving. Again, let it sit until the catalytic converter was replaced and it was running fine until yesterday it shut off while I was at a red light immediately turned on and made it work. On my way home it shut off again while I was slowing my into the turn to my home and wouldn’t turn in for ten minutes. Had the distributor cap and spark plug replaced bc I got a code saying misfire on cylinder 4. This morning on my way the engine shut off again when I slowed down to turn into my job and wouldn’t start again for about 10 minutes. I honestly don’t know what it could be.
