Good afternoon

When it will not start, did you check for spark or fuel?

Yes, compression is fine. It will start and run when is cold but when you turn it off it will not start back up.

Okay, when it stops, check for spark and fuel. One of them will be missing.

Both are there. It fires and gets fuel, you can see the fuel spraying into the throttle body.

It is possible but needs to be confirmed when the issue happens.

That is the ESC module. That will not cause it to not start or cut out.

The pickup module in the distributer was the cause

Good find. Very common failure for no spark.
