At the first ride since winter, was running great until accelerated...quit and wouldn't restart, had to be towed in. Prior to quitting it ran GREAT then acted like it had water in fuel, added dry gas & new fuel. Again idled rough & stalled out, then wouldn't start. Cleaned fuel filter at back back of engine. Changed plugs, ran better, but has a miss in it. Operated for appx 45 min, felt like it missing, but would intermittently ran smooth... before changing idle, missing & running rough again.

While running rough, it would then even out (whether accelerated or not)...then run rough again. Is there another filter that needs to be cleaned? something else ?

Sounds like a coil might be acting up causing an intermitent spark to plug. But first I would check cylinder compression.
