Sometimes it starts, sometimes it doesn't (heat-related)

1994 Ford Ranger with 162k miles. 2.3L 4 Cylinder - Had a heat wave up here in Michigan and that's when I noticed a problem and later the pattern: truck will turn over but not kick on if the engine is too warm (too warm means sitting in 90-degree heat for more than 3 hours or driving for more than 25 minutes). Just changed the plugs and wires. Electrical system seems to be running great. Also - if I try and try and try with no success, and I get out of the truck and give it a "15-minute break", then try again - it works. This one is definitely a problem for Dr. House...

I don't have A/C. Should I still proceed with your suggestion or would it have to be something different? Thanks!

Thanks for your response! I idoled my truck and watched the fan spin - it spins great! Should I still replace the fan clutch? Could it possibly be anything else? I've included some snapshots from various angles - I hope it helps:

Will do, sergeant! Is it easy to replace one (I don't even know what they look like)? I have no clue how to do it - and I'll get those fins sprayed out pronto!! Should I test it after I spray them out, or is that fan clutch a must-swap?
