So I have stalled, deloaded, and stalled again at the same weight as before. Should I deload one more time and try again?

I am thinking of upping the weight and going for 3 or 5 sets of 3. Once I go up 10 or 15 pounds, I will go back to the 3 sets of 5 at the stalled weight to see if that will break the plateau. Does anybody have any thoughts?

Every other lift is going up so I don't think it is a diet or sleep thing. Any ideas would be appreciated.
