Why am I still having intermittent Starting Issues???
I had intermittent problems with a (hanging head low) Ford gasser. Rebuilt starter acted mint for a couple of months.
Then... . I began to have troubles similar to whatyou are describing.
I refused to believe it was the starter itself. Checked and replaced all the electrical stuff including the battery.
Finally I pulled it off and when I shook it it sounded like a bucket of bolts. The front bushing was almost non-existant. It was rattling. It was causing the starter to side load so severely that the starter could not turn. Loaded the whole system down... all it would do was "click,click" when I turned the key.
New starter, never again a problem... with the engine starting that is.
