The motor looses power, and will sometimes gain it back while cutting. Sometimes it will run fine for long a couple of hours, other times it runs with loss of power the whole time I'm cutting. I've used carb/injector cleaner in the fuel. Bought the lawn tractor new in 2007, has a little less than 400 hours on it. When the power drops, I can smell gas while running.
 
Well first look at the complete length of fuel line from tank to pump/carb. Generally the engine mfgrs have a better quality
fuel line, which of course is closer to the engine, the run to the tank usually cracks first.
 
Possible that engine is running on one cylinder intermittently. May have plug/ignition module problem
