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!
