Did you change fuel cap? Did try the tailpipe test?

If it runs with petrol in the throttle body, it is nothing to do with the ignition. If it was, it wouldn't run at all. Fuel pump issues.

It could be a few things. Components that work properly for a certain time and then fail usually do so because they've overheated- a few common ones are ignition coils, ignition modules, fuel pumps, and more. I'd check the crankshaft position sensor as well. Stop by an auto parts store and have them do a diagnostic scan with their obd2 scanner- this usually narrows it down to a few things or tells you exactly what the problem is and they'll gladly check it out for free!

Thanks & have a great day! See the picture below!

No, not here. If you have a crash, that will tell you.
Speak to your main GMC dealership for proper advice.

Sounds like a bad ignition key module. Should be on the steering column hidden under some trim.
