2013 American Strat. I don't think it's a problem with my technique because it resonates just fine on my mexican tele, although I imagine there still could be something I'm doing wrong, as the necks are so different.

What else could be causing this? I've set up/had this set up so many times
Your action sounds like it's a bit too low. With the rounder 9.5" fretboard radius that fender uses, a really low action can cause you to lose some sustain when you bend a note. Raise it a little bit and report back.
