Sounds like we have a connection issue if the engine will start fine and then it will stop.

So, let's start with this guide to see what we have and do not have when it is not starting:

Most likely this is going to be a spark or fuel issue as it would not lose compression intermittently.

So here are two guides that will get us further down that road:

https://www.2carpros.com/articles/how-to-test-an-ignition-system

Once we know if we are losing spark or fuel then we will be able to better determine what the issue is.

Please let us know what you find, and we can go from there.

Thanks
