Mower starts and runs for approximately 1 minute and then it studers and stops. I try to start it and will not work even choking it. I wait a couple of minutes and starts especially when I engage the choke.
I had a bad run of watery gas which caused this same symptom. turns out some how i was getting water in the gas not sure if it was someone sabotaging the gas can or if there was a crack allowing rain water but after many issues with starting al of my lawn equipment i finally got a jar and poured the gas into it and discovered gas 2/3 water 1/3 i had to separate the gas from the water and clean out the carbs on all my equipment finally resolved the issue bought new storage containers and no more issues. replace spark plugs as well water tends to ruin the spark plugs fast hope this helps.
Try cleaning the small vent hole in the gas cap.this happened to me

Well this could be a couple of things first thing first is check the air filter and make sure its clean you can blow it with air or pore gas over it and clean it make sure you let it dry before reinserting
second im assuming this is the first time you have used it this year if so the gas you have in it hasnt been sitting in it all year has it like anything else gas gets old
third alot of times you can let it run for a while with the choke out then slowly pushing it in
fourth you could have water in the gas remove the tank and empty it remove the spark plug turn the engine 4 or 5 times only bumping it dont hold it down this will blow some of the water out then dry the spark plug off and replace it
if this doesnt help it could possibly be carburetor problems

It sounds like the carburetor is running out of fuel.First make sure the tank is full then loosen or remove the gas cap when it starts sputtering to see if that corrects the problem. Then with engine off remove the fuel line that goes from the tank to the fuel pump,hold it low and see if any fuel flows out of it,if not lightly blow air backwards to the tank,(with fuel cap off),then see if the line is plugged. Next remove the fuel line that goes to carburetor from the fuel pump,crank the engine and see if any fuel flows,if so the carburetor should be cleaned by removing it and disassembling it.

carb dirty, jets partially plugged, float sticking. Not so uncommon problem and is caused by the fuel left in the carb over the winter gumming up (going bad). You can attempt to clean this on your own if you are somewhat mechanically inclined. Search small engine repair and it will give you a generic breakdown of the parts in a small engine carb. If not the, to have someone overhaul a small engine carb will run you about $120 including parts (at least around VA).

filter maybe very dirty, you may need a new spark plug, you're carberator may have just a spec of debris in it , all things that happened to us also, this man is a wizard with small engines..www.belgiumsmallengine.com
