I have a Big Ten that won't start for anything after its run for a while. It looks to me like it is vapor locking. I would just put clothes pins on the line to absorb the heat, but it is a rubber flexi hose. Any advise is appreciated, do I need to run the fuel line a different way, or just get a new fuel line made of different material? Thanks!

If it is run the way it would have been run, from the factory. It is most likely not the problem. I would take the carb off and clean it really good. Replace the filter and check to make sure all of your lines are clear.

Next time it does this, check the coil for spark. Old coils have a habit of breaking down when they are hot and not making spark.

I'll try looking at the coil, I just cleaned the carburetor and bought all new gaskets for it, so that must be it.

If the engine is running hot it will increase the tendency to vapour lock. Make sure your cooling fins and flywheel cover are clean.

I agree with the others to check the coil. I had an 8hp B & S motor that would quit when the it got hot. It ended up being the coil. Hope you are able to get it fixed soon!

It will run as long as it has gas, it just won't crank up once I turn it off. Does anyone have a coil they could recommend to me? I am going to replace it and see how that does.
