It's just a little YardMan push mower with a 5HP Briggs & Stratton, it's a little over a year old and has always ran great. The last time I used it it died on me. If I push the primer bulb it will start again until it burns out that fuel, then it dies. When it's cold it will fire right up and then stall after about 5 or 10 minutes, but then you have to wait awhile before it will run again. I JUST changed the spark plug and the air filter thinking that might be the problem but it made no difference. It has a full tank of fresh fuel so I'm not sure what to check next. Thanks in advance for any suggestions.

That engine has a diaphram carburetor, and it sounds like that is the issue. It is a fairly easy job to remove the carb and install a rebuild kit in it. I have found problems with several of these carbs and a rebuild kit takes care of it. Take care with the linkage and springs that attach the governor to the carb. Sometimes taking a digital photo of it before you take it apart helps in getting it back together correctly.

First check the air filter and see if it's clogged. If it's dirty, clean the foam filter with gasoline, then a hot, soapy bath and clean rinse and dry it. Then a light saturation with regular motor oil to help trap dirt. Also, clean all the cooling fins of debris, dirt and grime with an engine cleaner, then hose off, protecting the carburetor from water with a baggie and a rubber band around it. Third thing to check is the motor oil itself, air-cooled engines use the oil to cool off and will shut down when they get too hot. If it's really black, thick or even too low, it could cause the shut downs you're experiencing.

It is more likely your choke. You are probably not able to turn it off. Check the mechanism. The age precludes it being an adjustment problem which is a possibility. The other is that you are forgetting to push the choke in when it warms up (unlikely).

Sounds like a fuel-line problem, either the actual fuel line itself, the fuel filter, or the choke...had the same problem with my pressure-washer, turned out to be the choke.

You might check to ensure that the carb is tighly bolted down, if you have a minor vacuum leak that gets larger as the block warms up.
