The starting issue, can be several things. Like rrlund says, could be the neutral switch, high resistance, loose connections, loose in the transmission.
Before doing any tests, be sure transmission is in neutral!!! The engine could crank at any time during a test!
It could be the starter brushes. The solenoid windings ground through the starter brushes. If they are worn or greasy, the solenoid will not pull in. Connect a test light from the starter lug to ground. Try the starter until it fails. If the light is glowing, the brushes are not making connection.
Could be the solenoid. If the above test passes, connect the test light to the "s" terminal on the solenoid, try the starter. If the light glows bright, the solenoid is probably weak. Carefully try jumping from the battery terminal to the "s" terminal with a screwdriver. If the solenoid doesn't pull in, only sparks, and you know the battery is hot, it's the solenoid.
If jumping the solenoid with a screwdriver makes it pull in, the problem is likely voltage drop from the ignition switch. This could also involve the neutral switch. If the neutral switch checks out, a simple fix is to add a starter relay. A Ford type fender mount starter solenoid is mounted near the starter. The wire to the "s" terminal is used to energize the Ford solenoid, it in turn supplies power to the "s" terminal, eliminating the excessive voltage drop.
