Weirdest Non-Starting Problem

[GCPRO]

So, this past weekend I replaced the starter motor with a different brand - Bosch. So far the beast is working great. The symptoms support a "limp" starter in that repeated key clicking would eventually get it to turn over. Also, it seemed to be more likely not to start when the engine was hot and then sat for a few minutes (increasing cylinder gas pressure).

I had ignored this possibility because I had replaced the starter before a couple times with no apparent long term fix (as I recall now, it did work OK for a month after replacement). But, being a cheap SOB, I replaced the starter with the same cheapest model from the same supplier. The Bosch certainly has more torque.

Consider this one closed unless (until) I return with the bad news. Thanks for the input.
