97 F250 won't crank

My '97 F-250 has been acting strange lately. It has been acting like the batteries are nearly dead. It will do a very slow long crank but eventually will start up. My daughter has been taking it out on very short runs and I assumed it was the batteries not getting enough time to recharge. So I took it out on the highway for a good run and it drove fine.

Next morning it was the same issue on starting so I threw the battery charger on the batteries separately. Same problem next morning so I decided to take it to the parts store and they load tested the batteries, and the starter. All checked out fine. This morning it was unusually slow to crank but started after 45 seconds or so. The truck wouldn't start at all when it was time for her to come home from work.

I went to give it a jump start but it won't crank. The power seems to be fine, the lights are bright, the WTS light comes on and then off a few seconds later. It is nearly 100 degrees outside so it doesn't need the glow plugs.

It is sitting in the parking lot right now so I am doing some research before I go back. I replaced the CPS around 40k miles ago. It doesn't smoke when it runs and normally runs great.

So I need a list of things to check when I go back. If there is something I can do to get it started long enough to get home, that would be great. It is literally less than 1/4 mile from home.

I replaced the lock cylinders and ignition cylinder a few weeks ago and this is roughly when the problem started. It doesn't seem like they would be related but stranger things have happened.

Turns out it was the starter itself. I bought a starter relay before heading back to the parking lot but I had a solid 12v across the big terminals in the relay when the key was turned.
I pulled the starter and took it to the parts store. On the test bench it just hummed and refused to spin. It was way too dark to put it in last night so I went this morning. It started on the first crank like it was a brand new engine. I wish I still started that well in the mornings. ;-)
