Assuming you've already been through the power manager options, the 
usual troubleshooting ideas are to try things like "acpi=off" in the 
kernel command when it is booting.
(The other boot options are at 
https://docs.kernel.org/arch/x86/x86_64/boot-options.html )

Also, as Jim mentioned, pay attention to if it the symptoms are 
identical with and without the power cable plugged in.

The other big thing to look at is the graphics driver, as that it tied 
into the suspend process. I had trouble with the nvidia one (it is on my 
list to go back and try again in case a recent update has fixed the 
bug), so have been using the nouveau one. Each has their own quirks.

As it is the latest Ubuntu, are you using Wayland?
