80 HP 912UL will not start

I have been having intermittent starting problems for a while now. Currently the engine will not start at a all. I have done some research yesterday and came away with the tip to heat the cdi units with a hot air gun. I charged the battery today for 4 hours to be sure it was in good condition. The engine would not start. I heated the top cdi with a hot air gun on low setting for apron. 10 seconds. The engine tried to start but sputtered. I felt the top cdi and it was already cool. I heated the cdi again for a few seconds longer this time. The engine immediately started. My engine was made in 2007 and installed in a 2008 aircraft. It has approximately 365 hours on it.
I am ready to order a soft start kit from Lockwood but they are out of stock. Apparently all the dealers have the same kit on sale now. I will check around for availability Wednesday.
I crank the engine with the mags off to burp the engine. I wonder if that played a role in the premature demise of the cdi modules?
I seem to recall a posting somewhere that there was a bunch of weak modules in a certain year that were prone to early failure. Are there any comments about that?
