Lawn Mower starts Easy and Stalls repeatedly. How do I fix? I have a Troy-Bilt 21 surrounded by. 0650 series push lawn mower...

I have a Troy-Bilt 21 surrounded by. 0650 series push lawn mower near a 6.5 hp Briggs & Stratton engine. It starts fine and then stops at regular intervals. You own to prime it again and then it will run a while and afterwards stop. I have replaced the spark plug, the atmosphere filter, changed the oil and no correct in activities. What should I try next?
