Hello,
So, does the engine just stalls all of a sudden as you are driving?
Are you able to start it back up afterwards?
This could be due to a faulty crank position sensor.
Faulty crank sensor won't be able to send the proper signal to the ECM and that can trigger the engine shutdown. After the shut down the engine may or may not start back up.
Take a look at these helpful guides:

I have attached diagrams below for your reference.
Let me know of any questions.
Thank you.

When it first started happening the engine would start up again but recently it didn’t want to start a couple of days ago.

So, it just cranks and cranks but does not start?
This could be due to a bad crank sensor.
Are you getting any codes?
