latest news on my starting problem:

I finally had a chance to take the car to my regular, trusted mechanic.

-He's ruled out the starter & starter solenoid--tested both

-He's ruled out neutral safety switch

-Battery is strong

-Glow plug relay is good

-He doesn't think it's ignition switch

He's been having trouble getting the car to not start, actually.

I gave him some tips (ha)--

The problem occurs after I have been driving for more than 10 minutes or so--seems that the longer I drive, the more likely the problem is to occur. Quite simply I turn the car off, and try to start it again and it doesn't turn over--I hear a click (maybe the ignition switch?), and that's it. If i leave it for about 10-30 minutes it will start.

Sorry if i'm repeating myself in this post, but wanted to save time for someone new to it who wants to post a reply.

suggestions, please....
