MS 361 possible coil problems

[Cedar Row]

I have replaced the coil on a 361 3 times in about 6 years, now I have a "no start when hot" problem with the saw. I have checked the other possibilities, seems like it is the coil. Is it likely that a hot coil would malfunction (saw starts cold relatively easily, runs fine while cutting, will not start after it is shut off. Will restart again when cold) when hot? Old bad coils had no spark at all. Anyone else have this problem with a 361? Also, Is the newer version of the coil any better?

i had it once, i reset the spark gap with a business card and blew it out with air. i also changed the fuel line.i thought for sure it was inconsistant spark, mine is about a 2009 to 2008. still original coil.
