You’ll need to boot up under an external OS installer USB thumb drive to properly format your SSD How to create a bootable macOS Mojave installer drive. You need to be using GUID with either a Journaled file system or the newer APFS used in High Sierra or Mojave MacOS’s How to format a drive on a Mac
In addition, your systems firmware may need updating which the installer drive will also do for you.

Is it like that loading bar at the bottom of the screen not in the middle where it goes very slowly to full then shut off? I get that with faulty SSDs that get stuck in read-only mode and have a corrupt file system.

Ben, correct the SSD needs to be reformatted and needs to be done from an external drive. And it needs to be the correct version of drive as well.
