Will it start up when it dies with starting fluid. <br>

Ok, I'm out of ideas. Requesting new ones.<br>
<br>
I have a Craftsman walk-behind mower with a 163cc Briggs & Stratton 4-stroke engine ( engine: 104m02-0008-f1 to be precise ). It's only 3 or 4 years old, but it will not run. And it's starting to piss me off.<br>
<br>
It starts normally ( no manual prime or choke, so it takes ~3 pulls but it always has ), and runs fine for less than 5 minutes. After that, it surges rhythmically and after a minute or so of that, dies. Following that, it will not re-start until allowed to rest for a few minutes.<br>
<br>
I have installed a new plug, new air filter, new carburetor, and new ignitor. I checked and set the gap on the plug and the ignitor to spec ( .030" and .006-.014" respectively ). Has clean oil, and brand new gas. Fuel screen in the tank is clean, as is the fuel hose to the carb. Carb bowl has fuel.<br>
<br>
What else can be wrong with it? It seems to be heat-related, but it has no cooling system.<br>
<br>
Thanks.<br>
