Should driveway/walkway pavers be top-dressed, i.e., re-sanded periodically? Mine are 3 years old. I have the drive & walkway washed and sealed every 12 to 18 months. But I'm starting to see widening gaps between some blocks. With all the recent heavy rains, I'm concerned the underlying sand is washing away.

What do you do?

Call the company that installed them for advice.

Yes. They do require periodically having sand added to them, as well as being sealed. Most companies recommended sealing them every 2-3 years.
