Problem of 2003 90 horse stalling under load

[Lowe180]

Having issues with my 2003 johnson 90 horse. Runs fine at initial start. Problem begins after leaving 1st stop. Engine stars fine then dies when put into gear. I've done the following but has not helped:
1-decarbed with engine tuner
2-changed plugs
3-treated gas with sea foam
4-changed primer bulb

Problem seems to be getting worse with each trip, any advice would be greatly appreciated. Thanks

Check compression, may need to clean carbs.
