Thanks for helping with the last problem!

This is a problem that I originally had and still is NOT fixed.

The boat fires right up when it's cold. I allow it to warm up at the ramp then off we go. If I cruise between 1000-1500 rpms she will pop, shutter and die. I try not to let this happen and usually make a run for it and get her up to the cruising rpms between 3000-3500 where it runs ALMOST flawlessly. It will occasionally sound like its dropping 100 rpms like its wanting to bog down a little and I just tap the throttle forward and no problem, she runs great. When I come in after we've been out running back to the dock same thing. I drop me speed to cut my wake and bam she dies.
Note that after the boat is warm and I stop and try to restart it sometimes has to crank over for 20- 30 seconds and I have to rev it up to get it to start and also that it dies at an idle.

This is very concerning because I have my friends and family aboard and our water in Alaska can turn to very unforgiving seas in a hurry.

PS I Removed the air cleaner and no fuel is dripping from the choke.new ignition control module,coil,cap,rotor,plugs,wire. fuel tank is clean, fuel is brand new, fuel filter is new.
