I tried executing your snippet and wound up with an "Unable to fit initial boundary conditions" error.
What's wrong?
                                                                                                        Jan M. ('_')
 
P.S. If your interest is only in the numerical evaluation of the DE, I suggest you use NDSolve[] instead.

Did you mean this?

DSolve[{A1 x^2 y''[x]+A2 x^2 y'[x]^2+A3 x y[x] y[x]==
A4 x^3 y[x]^4+A5 x^2 y[x]^3,y'[0]==0,y[a]==A6},y[x],x]
