(Found) Make sleeps for 5000 years

Hi all
I did ask this once before but through reversing lately I lost the name of this book.
It starts with a man's wife dieing. He cannot deal with it and sells everything to build a vault so he can sleep for 500 years. When he wakes he has a long beard etc. He can hear a noise at the steel door. After his rehabilitation he decides to leave. He realises he has been asleep 5000 years. The noise he heard was treated gnawing at the door, and they were almost through! He walks out into a very different world.
Any help would be great

Star Gods by Jack Lovejoy

From Goodreads:-

When his wife and son are killed in a freak auto accident, professor Glenn Randolf looks to the future for a better world. He proves his theory of induced hibernation by placing himself in his own invention, a time capsule, and falls into a 375 year sleep.

Randolf awakes to the horrors of a barren land populated by savage mutants, but finds his way to an oasis called "The Holy City" where a beautiful society of humans live and practice a religion devoted to gods from the stars - aliens who are sapping the genes of the strongest humans to strengthen their own civilization. Randolf is forced to use every ounce of physical power and cunning to save his life...and the community of beautiful Earth people from extinction
