70s/80s Scifi novel Space adventurers in a deadly alien pyramid

[Todd Risser]

Late 70s or early 80s sci-fi, read it early in high school. The plot began with a multi-species group of space-faring adventurers trying to make it past traps in an ancient pyramid to acquire vast treasure. All but 1 or 2 were killed. The book had a companion book set in the same universe. In both books an enslaved race of slow-thinking but very strong humanoids were involved. This race had a huge long name like 'pourudoloupolus.' In the book about the treasure hunt, it's one of that race who survives with the captain of the ship. I think its the second book in which that character becomes a Moses-like liberator for his species. If I recall, civilization is winding down, and tech like space craft are becoming harder to repair Nd keep in the air.

I'm also trying to find that same book....no idea of it's title or author!

Hmmmm this reminds me vaguely of a side plot of the now non-canon star wars books. It's been too long though to remember much, but here's a plot summary:

A very long shot but could this be Eando Binder’s Puzzle of the Space Pyramids? It has been reprinted many times, over many decades.

I'm not 100% sure but I think this question has already been answered, somewhere in this forum (I saw it one day!)

Possibly this: Sci Fi Archaeology book

Sounds vaguely like a story in Analog magazine going back about 10 years...
