I am with Benz on this one ! I'm not one to just throw parts at a problem, I like to eventually find the cause and the fix. But if 170 bucks gives you peace of mind ? I'd go for it ! The difference between your issue and mine is that mine ran fine for a bit then shut down all together and would not turn over till it cooled off it seemed. Well except for the one time I gave the Control Module a lil love tap outta frustration. The darn thing started up immediately.
Since replacing the module I have not had any more NO START issues.

Just my Dos Centavos !
