engine pops & sometimes dies

[mojos]

Hi guys ,I am new to the forum & first off would like to say hello to everyone.My problem is I have a Kawasaki fh 380 v 23 hp.It was running fine so far this season & all of a sudden started popping & would die when under a load,meaning with the blades on & trying to mow.I ck'd the plugs drained off the tanks,cleaned the filter & removed the carb.cleaned & blew out the passages with air.Sometimes it will run fine,shut it off & restart & it starts to pop again,any thoughts?,thanks ps this is on a skag 52" tiger cub

I'm not a great mechanic or diagnostician but maybe the fuel pump is on the way out, a fuel filter, debris & oil clumped and plugging the cooling fins on cylinders.

Anything that reduces cooling efficiency will start showing in performance this time of the season.

My 26 efi did the same thing, At first it would come and go then it stayed and then quit. My fuel pump was bad
