Three days ago I replaced the section of fuel hose on one of these between the fuel filter and carb. It had cracks that would let air into it causing a similar situation to yours. I found the problem by injecting air from an air hose nozzle into the gas tank with a rag taking up the major dimension difference between the air nozzle and the 2 inch gas cap which was removed. Be extremely careful not to blow up the tank or otherwise cause excessive pressure on the fuel system, but when I then looked for any leaks, I found a half-cup of gasoline on the floor of the shop under the carb area which is plenty dangerous enough. I you find ANY wetness along the length of the fuel hose it is time for a new hose, mine cost me $1.60 a foot at NAPA for generic 1/4" gas hose. You don't have to pay more.
As a prophylactic measure you also don't need any excuse for just changing out your old fuel lines...
I had the same problem it turned out to be dirty fuel...i flushed the dirty fule out cleaned fuel filter it now runs well cutts well im happy
Had the same problem with an almost new Craftsman w/ Intek 20.0 HP. Check all the "usual suspects" and had to have a tech come out. He had me start it. It ran for a few minutes and stopped (per usual). He immediately went to the Anti-Backfire solenoid. It is an electrically operated "plunger-style" fuel line blocker. They are famous for going bad. The part is about $65 and its sole purpose is to starve the engine of its fuel supply at shutdown so it won't backfire. If it is disabled, the user must throttle the engine down for 10 seconds or so before turning the key off in order to avoid backfires. Gee... let's see, 10 seconds of my time each time I use the mower vs $65 part ... No contest! Remove the solenoid, take a pair of electrician side cutters and snip off the tip of the plunger and reinstall it. Problem solved ! ! !
