What does it mean when there is sus written after a chord? Does it mean to hold or sustain the chord?

Sus is an abbreviation for suspended, not sustained, so no, you aren't being told to hold the chord. There are two commonly used types of suspended chords:
sus4 - A sus4 chord replaces the 3rd scale degree in a chord with the 4th scale degree. So a triad spelled 1,3,5 becomes 1,4,5. the third degree is replaced by the fourth. For example, a DMajor chord, D,F#,A becomes D,G,A or Dsus4. The middle note or the third note is raised by a half step.
sus2 - The sus2 chord follows the pattern 1, TWO, 5, so if in a sus4 chord you play the root, fourth and fifth degrees, for a sus2 chord you play the root, second and fifth degrees. For example a Dsus2 chord is D,E,A. The middle note is lowered a half step.
That is very often what people mean when they day or write a sus chord, but in practice, alot of players include 3rd in their voicings, usually above the 4. Mark Levine's The Jazz Theory Book ends up defining a sus chord something like,,,a sus chord is a dominant 7 chord where the 4 isn't an "avoid" note.
