Take a drastic turn and do something completely different.
I've been making dubstep, dub, and hip hop sort of beats for a while now and i just hit a wall not to long ago.
So what i did was make some trance(sort of i suppose, but it'd be more like indie trance -_-), break beat, and a form of jazz funk.
The sound components of today's EDM, really doesn't allow for much musicality in terms of different dynamic perspectives.
Just keep working on stuff and continue to grow. You'll hit snags like this all the time, and hopefully they'll become fewer and far between.
You should recognize that doing the same thing over and over again, is good for learning. But at some point, you get rather tired of it and need a shake up.
That's not to say that you shouldn't ever return to what you started out with, but if you're continuously looking for something new, you're eventually going to be at your wits end of discovery.
Observe every thing you've done, and apply What you know now, to what you did in the past.
Constantly creating is a difficult task to do. That's why it's important to collect all of what you know and what you've did, and turn those ideas and concepts into something new.
You probably have more than enough to work with if you just sit down and collect yourself, and apply what's already existing in new ways.
