I have a 2000 Yamaha 150 that stalls at idle after being run for a while. Just had both fuel pumps replaced by a Yamaha dealer and had fresh plugs installed. Motor seems to run good until after it is up to operating tempeture. Then either stalls when idleing or when put into gear. It also runs fine above idle speed. I've done a compressino check and tried to check all fuel lines when seem to be good. Any ideas would be appreciated.
