It sounds to me like it's a problem that is related to something reaching a certain temperature or possibly a fuel restriction. 

Have you checked fuel flow at the carburetor? 

Doc is probably right. If you need a new coil, I usually get parts from Brillman.

I prefer to diagnose the problem before throwing new parts on it. If it's the coil, the spark will be weak, very weak or maybe not at all. If it restarts cold, pull off a plug wire while running and see how far it will jump a spark to the engine block/head. When it warms up enough to start to falter, recheck and see if the spark intensity is the same or weaker.  If you haven't had the coil replaced, it's a fairly good bet it needs it as this is what they do when they get old.

Thanks. The mag was just rebuilt last month, which included a new coil and points. I can still check the spark as Doc suggested, but would appreciate any other ideas. Thanks.

Wasn't there a post about a collapsing hose or gas tank vent clog doing something like this to someone early last year?

There are a lot of inferior Chinese made parts out there. Just because it's new, doesn't mean it's good. I went through a bunch of condensors on one of my (distributor) WD45 a couple years ago. One wouldn't even start the tractor.
