Have had a light L130 JD for years. Has twin vertical Kohler in it. Today was mowing in yard and it just quit like running out of gas. Would fire some on choke at first, then not. Took off air cleaner and sprayed start fluid past it and it would run on that. SO, guess not getting gas. See thru filter looked full and fine. This has Vacuum pulse pump on engine head. Pulled the line with filter from that pump and lowered it down, hoping to see it run fuel out. BUT, darn thing made lots of sucking noise, heard big action in gas tank, then the gas all sucked out of filter back to tank, the noise quit. Weird! It's like the gas tank was under vacuum somehow and when line was off, it sucked air back in, gas with it. Put the hose back on, cranked a little on choke, fired right off and finished the lawn and put away. This is oddest no-start problem I've ever had. When I filled tank, I did overflow and had right up to top of the neck, and put cap on anyway. This do something to the vent in cap?? Sure glad it wasn't some parts replacement needed, supposed to rain all week-end and didn't want it out all that time. I've heard of Vapor Lock on cars from heat, but this tank is in back under seat and never warm on the lines or nothing. Got me stumped!
What The? New One To Me!

i would think you vapor locked the tank, possibly check and see if the o ring or rubber flapper is degenerating

Sounds like the Vent in the Gas cap is either clogged up "if its just a hole" or stuck shut if it has 1 of those rubber valves.
LOL looks like your not the only 1 this has happened to.

my guess would be the vent in the cap. However- when it's usually the cap vent issue, it will run a couple minutes and then quit but it usually does run for at least a minute or two.
