CV15 fuel stops flowing - engine dies

All fuel filters are not created equal. There are the screen filters, which I think flow the best for gravity feed fuel systems, then the Micron family of filters - 10, 15, 30, 51, 7-11, 70-80, 75, 8-10, 80 microns......take your pick!
 
It all depends on the porosity of the paper. If the paper is fine enough then surface tension can cause fuel to stop flowing. I have had people bring in mowers doing the same thing the OP is having and they put in a paper filter in a gravity system.
 
Thanks guys. I'm gonna try the right fuel filter Hammermechanic suggested, if that's not it I can use it on something else. It's worth a shot, and I came her for advice!
 
While the various types of fuel filters offer differing flow rates and protect against different sizes particles (micron), i wouldn't think this to be the issue unless the problem started immediately after you installed it. If this is not the case you have only a few possible causes: clog in lines/pickup, fuel pump and carburetor. Ethanol and contamination can wreak havoc on fuel systems, especially over time. Filter are cheap so go ahead and buy the original filter but if and then that doesn't work, check the fuel pump. It's not exactly safe, you would need safety glasses and a face shield, but you could remove the fuel line that connects the fuel crossover tube to the carb and replace with a spare piece of hose put into a gas can or jug and crank the engine and verify that the pump is actually moving fuel.
 
Thanks for the input everyone! So, yesterday I changed to the filter Hammermechanic suggested, and that seemed to do the trick! I cut grass for over an hour and didn't have any problems! Hammermechanic thank you sir!
