I'd replace the plug first.
If that isn't the issue, I'd go over the entire ignition system from top to bottom.
When yu changed the coil, did you also change the plug wire? sometimes they can crack, and they will arc to ground, so that the plug gets no spark....until the wire warms up and the crack in it closes enough that it doesn't arc anymore.

Bike cuts out at running temperature

You actually may have two problems. First, if you have a spark from a coil, find out why. May be a bad or loose connection. when coils get hot their resistance increases. A leak or bad connection will show up quicker when hot. If the spark comes from the body of the coil, replace it.
Second, your starter may be breaking down when hot. Check the brushes and coils in the starter motor. The same discussion about loose connections also will apply to the starter.
good luck

Starts ok but only running on two cilinders

What have you done if anything to check out this problem?
Several causes could be: 1. Not getting fuel do to clogged jet in the carbs for those cylinders. 2. Fould plugs in those cylinders. 3. Not getting spark to those cylinders/bad coil 4. no compression in cylinders that don't fire.
So run the bike and determine which cylinders are not firing for sure. use a squirtgun and hit the header with some water. running cylinders with smoke the water. non running will not. Then remove and replace the plugs.(look at old ones, all oily=bad) See if they are wet and shiny but not black...Not shiny=no fuel. Tear carbs apart and clean. Check to see if you have spark leave spark plugs unintsalled from motor but installed in spark plug boot. see if they spark when you start it. Do a compression check. wet and dry. could be rings or valves.
If the bike was sitting for a while then probably clogged jets...This is where stabil comes in handy or else drain the bike at the end of the season.

Snow blower spark plug replacement

I would check it at the start of every season and clean it. If you note that it seems to be running rich and might have fouled the plug, you can always pull it and check it again. Probably not a bad idea to check it before you put it away for the season. As for replacement, it depends on condition. I would think that you should get two or three season's use out of it before needing to replace it, at least.
