two things could be happening.......first is vapor lock......make sure you breather tube is clear and working........next is ....it could have a bad ignition coil on it.....after the coil gets hot the spark can become irratic or just not work any more.....

If the fuel line is dry after the fuel pump its usally the diaphram thats stuffed does it have a fuel tap in place? is it off? also i know with nem mowers just been come over from freight the fuel filter is full of oil for the first start up as the valves need lubrication first startup... take the fuel line off from the carb just have it hanging down for a start, then crank the mower over, you should then have fuel coming out of fuel line by then... see if that helps jay QLD AUS

Sounds like a fouled needle seat, or the float bowl is failing.
Pulling your Carb, and cleaning it out. COMPLETELY.
A ton of people think "a shot of carb cleaner, and a gasket kit" is a carb fix. It is NOT, and WILL NOT fix a carb, if the problem isn't gaskets, and shots of cleaner!
Meaning, if she is running too rich, then too much fuel (as you said), and fouling plugs, remember there are only a VERY few things in the carb anyway as it is.
1. Needle Seat
2. Fuel Float Bowl
4. Fuel Ports
5. Air Ports
My advice: (This assumes you HAVE NOT ADJUSTED YOUR CARB OUT OF DEFAULT!)
Pull the carb (Carefully!) and tear it COMPLETELY down (Carefully!). Note where stuff went, take your time, be patient.
When you have everything but the butterfly plates out, run some Gum-Out through each and every port, after you made sure to pull the Float Bowl, and the Needle Valve (and remembered how they went back in there!). Take some compressed air, and follow through (CAREFULLY!) on each and every port. Clean the very TIP of the Needle Valve. Shake your plastic Float Bowl. Does it have liquid inside? She has a hole in her. REPLACE!
If not, then this exercise was cleaning crud/residue that is ALWAYS building up inside carbs in 2/4-stroke engines world wide, every day. NOW do a "carb gasket rebuild".
Note: Remember that sometimes, crud/junk is testy, and stubborn as a mule to get out. Double check any screens above/below your Needle Seat and Valve. Remember that Needle Valves come with solid tips, and some with rubber tips. Regardless, be careful, and clean thoroughly! A Needle Seat that isn't getting closed, is a Needle Valve that is letting WAY too much fuel in!

SOURCE: spitting and sputtering
mine did the same, I found out that the high speed jet was clogged, I pulled the fuel line off the filtor(going to the carb), stuck the line into a mixture of half gas half carb cleaner, I fanned it up and in 2 or 3 minutes it started running well, hope this helps.
