John deere gx75, scratching my head.

I am currently working on a john deere gx75. It has a 9hp kawasaki. The internet and the JD parts guy tells me there is a igniter in the electrical system. But for the life of me, I cannot find it. Traced the wires and everything.
But in the diagram on the internet, is different than what I am looking at. I have a black, star shaped deal mounted by the solenoid. It has a diode symbol on it and stamped 5.4
Anywho, that diode isn't on the electrical diagram, that I can find anyway.

But long story short, this machine likes to die after running perfectly for 10-15 minutes, and not wanting to restart until it's cooled off.

Not trying to just throw parts at it, but after hearing about what it was doing I ordered a igniter with out even looking at the machine.

So far I've only cleaned out the carburetor,
Cleaned the ignition system,
New plug,
Coil reads 18.6k ohms.

A little confused about it. I would like to hear oth peoples thoughts and opinions.

Thanks in advance!
 
Do you have any idea how many different 9 hp models Kawasaki produces? We need ALL engine numbers of the ID tag to help you. Techs on this forum are good mechanics, but since COVID all psychic powers have been sucked out of us.
 
IF the star shape looks like this it is a voltage regulator.

Also JD Parts is indicating a FC290V-DS10, FS10, and GS10.

FS10 and GS10 is not showing an ignitor used. Can't find the DS10. On the JD site they are showing an ignitor but I think it is only for the DS10.

I agree with Star. From what I have found the GS10 does not use an igniter. Next time it happens check for spark. No spark means the coil is overheating and breaking down. Time to replace the coil.
 
Would you just pull the plug , ground to the block, and turn over the engine?

My only experience so far with testing coils is with the ohm meter.
 
If you don’t have an inline spark tester yes ground the plug to the block. Todays coils cannot be tested unless you have an expensive piece of equipment.
 
Houston, we got a problem here. The 21121-2084 coil is NLA from Kawasaki.

this what my distributor has posted.

I am planning on testing it tomorrow after I get off work. But for giggles I tried to find a replacement ignition coil, to find an idea on what it's going to cost. Apparently I can get one from John Deere,
But it is expensive lol
