After about 10 minutes of good mowing my Deere Lt 180 engine starts shutting down as if running out of gas. If I pull out on the choke it will recover and will run for a little while and starts all over. Replaced fuel filter, fuel pump, plugs, ignition coils, pulled gas tank and drained, blew thru gas lines, cleaned air filter and nothing helped. Thanks in advance for help. Bill. Engine: Kawasaki V-Twin,17 HP, FH500V, 4 cycle
Start from first principals and get an in line plug tester , about $ 10.
Install it so you can see it while you mow.
If it continues to flash while the engine is slowing down you have a fuel problem and if it stops flashing or flashes irregularly as the engine is slowing down you have an electrical problem.
Posting the engin make, model & numbers make helping you a lot easier.
Put some WD 40 ( or similar ) in a TRIGGER PACK NOT A SPRAY CAN and when the engine starts to die spray it liberally around the carb, manifold & head.
Clouds of white smoke or a significant change in engine speed = air leak
