I am looking for some advise on an issue I just started facing with my Exmark S series. I picked this up used last year with 1000 hours on it. I only use this to mow my 5 acres so not many hours are accumulating. Everything has been work fine until recently the mowing starts to bog down and eventually die after 30 - 45 minutes of mowing. Until then there is full power and all is good. I replaced the fuel filter, air filter, and oil. When the issue happens, the red indicator light comes on. After a few hours - everything is back to normal.
Does anyone have any suggestions on how to troubleshoot? Any guidance is greatly appreciated.
is it fuel injected? if so turn key on and off 3 times leaving it on on the third time count the flashes. its a 4 digit code. 10 flashes is a 0. so 10 1 7 4 would be a lean fuel mixture. it could flash out more than one 4 digit code. it will always flash out a 6 1 code at the end ps all codes start with 0 some start with 00

Thank you so much for the replies. I asked my local dealer about the codes and he said there's no way to ready them!!!! Lies
I'll check this out the next time it happens.
I did suspect overheating - but didnt know how to resolve - thanks for the advice on cleaning the fins around the engine.
This is a yearly must on ALL mower engines. Look in your engine manual. It will say it in there. Most people don't know about cleaning the block and cooling fins. If you've ever cut high grass or scaleped a yard or two, this is a must do. Some baggers trickle grass into the top of the engine where the cooling air goes into the block.
since it works for a while testing the connection wont tell you anything. but to test it unplug fuel pump, red wire will have power at all times with key on, 12 volts. computer grounds black wire to activate fuel pump. suspect bad fuel pump with your problem. to unplug lift up on white tab, will come up 1/8 inch then squeeze and pull connector up
