In addition to inspecting and cleaning the carb, have you tried loosening the gas cap and running it. If it isn't, I'd make the leap of faith that the ignition is probably OK and your problem is elsewhere(most likely fuel delivery). When the engine begins to shut down, if the spark is going away, that's a good indicator it is the cause of the shutdown. I have seen magnetos(ignition modules) be intermittent and the best way to check that is with a gap type tester that you leave in series with the plug and watch the spark with the engine running. It's typically either good or bad and the things that would cause it to change on a running motor are all pretty unlikely scenarios. The timing would not change on a running motor. I agree with 30YT that it's probably a fuel problem as opposed to ignition.
