You're probably running out of memory (=RAM).  Try editing the file
sage_vmx.vmx and increase the amount of RAM that is made available to
the vmware machine running Sage.  The default amount is very small.

Be way more precise.  How big is "big prime field"? Do you want
#E(F_p) = 4*n with n odd?  Do you require that #E(E_p)[2] = 4 too?
