Long Starting Problems?

Long Starting Problems?
I have a 1997 GMC Sierra 1500 (5.7L V8) that recently has been having a delayed/hard starting. In the mornings it cranks and starts fine, but after it's warm and running a while, it keeps cranking for a while before turning over (roughly about 5-10 seconds to start). It has never not started on me, but I know at some point it will. After starting, it runs fine with no issues.
Can anyone help me diagnose this issue? I'm thinking fuel filter or pressure regulator, or plugs and distributor cap/rotor, but would love to hear some different ideas to point towards as well, just in case.

I replaced the fuel filter yesterday because it was due anyway, but have not had a chance yet to see if it makes a difference.

Fuel Filter Replaed... New Starter Issue?
Over my last few cranks, it seems that a few time the starter is not catching the flywheel. Turn the key and the starter motor ignites, but not cranking (just the churning of the starter motor). It's not happening everytime and it'll turn over after trying it again, but it is happening on the first try.
Is there anything related to replacing the fuel filter that could be causing this, or is this a starter issue that just happens to fail?

Changing the fuel filter would not cause this. It is probably the bendix gear on the starter. If it is grinding, fix it fast before the flywheel is damaged beyond it's being usable.

Would it be recommended to try and repair the bendix gear or is this a replace the whole starter? I have never made this repair to a starter.
