John deere lx188 wont stay running

[briantbarton]

I have a john deere lx188 mower with a kawisaki engine. It stopped running so i replaced the coils. Now it runs for 5-6 minutes then quits, and wont start back up until motor cools. Any help would be appretiated

when you replaced the coils did you gap them

Does it have spark when it wont restart? It might be a fuel issue, vaporlock?

Try replacing the ignition module, when I replaced the module the first time they said that you normally replace the coil as well. But the ignition module is most likely your problem.

If the unit has spark and it still wont start. I would follow up by checking the fuel supply to the fuel pump and the fuel pump pressure. That LX series was good for getting junk in the fuel tank and plugging the lines. Also sometimes the fuel pickup line will pick up something from the tank and hold it there until the engine dies from fuel starvation and then it drops the debris back into the fuel tank?

i got the same problem with mine. Would you do me a big favor? Can you take a close up picture of the engine showing all the linkage to the carb. I took mine apart and now I don't know exactly how it goes back together. The diagrams don't help either.

I don't know what it is but it runs fine warms up and dies. Starts back up later and does the same thing. I checked everything fuel line wise. Gas cap, filter, line. As soon as it dies I up the line at the carb and theres plenty of gas in the bowl.

The backfire preventor on the bowl, thats not it.

I'm stumped.

I thought when a module goes bad, thats it. It gone.

That's what they told me, but I don't recommend it. I would not suggest replacing the coil every time the module goes out. When the module on mine went it was doing the same thing. But replacing the module fixed the problem. I would also try replacing the fuel solenoid on the carb bowl.
