Does anyone know why my 93 Buick Century 3.3 start after being drove for a while?

[SweetPea]

That's how it started, not starting after me driving it for long distances. I changed the starter, I discover after a few weeks the issue wasn't resolved so I change the battery. I am still dealing w/ it not starting, and at times it want even jump off! BUT all the electrical stuff like radio, power windows (the ones that work), headlights, they all work, it just want turn over, It want even attempt to turn over. I turn the ignition, and get nothing. I was told it could be the ignition switch OR the neutral safety switch? PLEASE HELP! I have put to much money in this car and it still isn't fixed! Any suggestions?

if it starts after sitting awhile im guessing the timing may be off.

My suggestion is a bad solinoid and or starter after heating up it weakens the starter and will not allow it to crank.
