motor will idle in gear fine for 15 min then rpms drop and motor dies. motor will run high rpms for a while then rpms may drop down gradually till it stalls. it will run wide open then when you back off throttle rpms drop and gradually dies. carbs have been done fuel pump diaphrams are new, no leaks in fuel lines or connectors. ive run it on external fuel tank, still no luck. PLEASE HELP. IT DOESNT MAKE A DIFFERENCE IF YOU PUSH THE CHOKE WHEN ITS DYING EITHER.

Might have the idle stabilizer checked.
