Do you any sense of power stoke?
EWS antenna failure is possible but rare compared to previously mentioned and most likely terminal if it occurs.

What has crank position sensor to do with starter activation?

Good point I crossed over from a different thread (crank no start).

Back to most likely switch or wiring to DME/EWS.

Thanks for all of the responses. How do I test the ignition switch, EWS, and other items mentioned? I took the cover off the old ignition switch and all contacts look good and clean.

What scanning tool are you using ? The suggestion above about the convenience relay is a solid one.

When you turn the key take note you do not have to hold for the crank. A timer takes over and cranked xx seconds. The circuits that control that havw relay/s that if faulty could give you the symptoms you describe.

I would splice a wire to the control wire for the starter solenoid or at the solenoid. When it doesn't crank you can put a voltmeter to the wire and to a ground and see if you have voltge on the control wire. Sound like you have a break in the wire that is intermittent.

@ual is correct feels like a broken wire but that “broken wire “ could just be a dirty contact on a relay

The starter solenoid is normally the relay, but since he replaced the starter I'm assuming the solenoid was replaced with the starter.
