No idea why a freewheel would work fine in the morning and poorly in the afternoon, but if it were me I'd just buy another 80's UG freewheel on eBay. Used ones with a 28 big cog in good condition were around $30 the last time I looked. They are very hard to kill, so of it looks good it probably is good. Yes, you will need the removal tool or a friend who has one or an LBS without a long line.

Freewheels are consumables the 600 is probably from 30 years ago..

$50 bike. Try the clean & lube, and if no success, pick up a new Shimano or Sunrace. It'll probably shift better with a new HG freewheel as well.

If anything, hot weather should make whatever's inside the freewheel thinner, so the pawls are looser, and more easily engage. Are we sure it's a freewheel problem ? Maybe the shifters are loosening up, and slipping a bit.
The only time I've had a freewheel or freehub spin free going forward, and create a "neutral" effect, is in extreme cold.

Have you checked chain and freewheel cogs for excessive wear?

i hear ya, but it happens so fast i was never able to catch it in the act. it never trys to change gears though. it slips and then it is fine for awhile. it does not chatter like it wants to change
