Troy Bilt Tiller runs and then dies

I have an older troy bilt horse rototiller with an 8 hp Briggs and Stratton engine, model no. 195437-0292-01. It has an ongoing problem. Starts fine, runs fine, until it gets warmed up. Runs fine, then dies, like someone flipped a switch. Starts right back up, runs, dies. Each time it runs for less time, until it won't run for a minute, then it won't start again. Walk away, let it cool down, and the cycle repeats again. I have rebuilt the carburetor, has brand new gas, gas tank is plastic so there are no bits of rust. I cannot figure this out, anyone have any ideas for me? Thanks.

Try loosening the fuel cap, it may not be venting properly. Have a good one. Geo

Thanks for the suggestion. Tried again with the cap very loose, same result, tiller runs for 3-5 min, abruptly dies. I can restart it easily, it runs for 1 min, dies. I can do this several more times, then tiller does not restart easily. If I let it cool down, it will start and repeat the whole cycle again.

Kind of sounds like fuel is barely trickling into the carburetor bowl fast enough to keep it running.

Sounds like a fuel starving, but it looks like that engine has the points/condenser. You may have a bad condenser or pitted points.
