That optical sensor that he is talking about will also cause other problems than just a hard start. Generally, you will also experience high RPM missing or missing throughout the RPM range. Have you pulled your codes?

Thank you steel i 'm thinking.like this It just seems to be unreliable voltage somewhere in the system. But as far as the codes i haven't done this yet. Tomorrow i'll call my mechanic and get him in the codes situation.
Back to the previous paragraph.
I can go start this kar right now and it will hit everyime, after its warmed up to operating temp. and it will hit everytime you crank it over in the garage or out in this awful high heat we'have been having she'll start. I even let it set after shutting her down.As then the engine temp rises 10 degrees or so and it still starts. I cleaned the battery posts again yesterday but i am thinking ---this week i'll brush them posts till they shine like new.See what that does.


The funny part is--if there is a funny part----is it could fix its self and i won't have a clue what was wrong.!!! You ever done this,it can be maddening for sure bob s

Once the engine shuts off, its does get a bit warmer since the hot coolant is no longer circulating. I notice this all the time on my LT1s. And with them being iron blocks, they take their sweet time coolin down. Are you running the orange Dexcool by any chance for coolant? If so, I recommend switching over to the green antifreeze. Several LT1 owners, including myself, have switched over to this and the engine seems to run a bit cooler. Plus its cheaper to replace too.

Intermittent problems can be a pain to diagnose that's for sure. Definitely sounds power related to me, unless you have a starter that is on it's way out. I would do as you are already doing, clean up all terminal connections and make 'em tight. If it keeps occurring move on to other things like bad cables, starter, or battery.
