   Our greens king VI gasoline engine starts fine, travels and mows properly until the engine just quits. It used to last about 9 sets of tees before shutting down but now it is more frequent. Its been sitting in our shop for awhile due to its issue. It will restart fine but quits quicker(maybe due to heat of engine, oil,…..?). Replaced fuel filters and carburetor, swapped fuel pumps, checked fuel lines, relays, diodes. Any thoughts or ideas?
   Thank you in advance for any help you may be able to provide.

   How long before starting back up, right away, or does it have to sit for a short period of time? You can hook an in-line spark tester and see if it's loosing spark when it starts to stall out. Also, common problem we often over look is the fuel cap, is it venting, or are you getting a vapor lock? switch caps or loosen up cap and see if it stays running or when it shuts off take cap loose and see if you hear pressure release from tank. I know I had a similar fuel issue with a Jac 3400, and there was a screen inside the tank, part of the petcock the was collapse ans sucked in from debris and would limit my fuel supply at fuel throttle. Started out far, and problem became quicker and quicker.
   
   Hope this helps

   check that the battery is being charged when running. Not sure about that unit but it may have a fuel shut off that is normaly closed requiring power to stay running . when the battery gets low it dies,sitting in the shop will somewhat recharge .

   Check your ground cable to the engine. The fuel pump needs constant voltage to work properly.

   when checking in line spark is that the same as removing plug keeping it in its boot and the bottom resting on some metal then turning over engine to see if its getting spark? If not can you explain? I see they sell in line spark testers at napa. If it is different and im not getting the in line spark what is the issue to be fixed? Im a 20 hat superintendent and learning to be a mechanic is one of the hats i wear. Thank you for any help

   An in line spark tester is just that in line. You leave the spark plug in the head and unhook the plug wire. You attach the spark tester between the spark plug and the plug wire. This allows you to observe the spark while the engine is running. Run the engine till it fails while observing the quality of spark. If spark remains as the engine stalls it is not an ignition problem but most likely a fuel problem. If the spark stops as the engine stalls than it is an ignition problem. Sometimes coils fail under high heat conditions. Or you could have a wiring issue or a safety switch problem.

   No need to explain it, Joseph nailed it on the head.
   
   Sometimes spark/coils short out if there is a bad ground, and I know many have suggested checking your ground. If you feel it's a fuel problem you can use a remote fuel source and see if that keeps it going, if not then you know where your problem is.
   
   Battery voltage was one mentioned too; place a load tester "get one @ NAPA, toaster style about 50 bucks" and place it on the battery with unit running and see if it's charging and what the output is. Turn off and apply load for recommend time, like 10 to 15 seconds is what on tester I believe and you can tell the integrity of you battery.
