Charging system cutting out

At night my charging system quits charging above, say 1,000 RPM (guess) but charges normally at low RPM. Any ideas?

A voltage regulator on its last legs maybe?

Check the gap on the crank position sensor. Should be 0.050", check it with a brass feeler gauge.

You might also want to look at the brushes in the alternator.

I had the same. Had it checked at the auto parts place. Found out it was the alternator. If yer handy, just replace the brushes. If not, they run about $250 w/exchange.
