Sorry for OT, but I in big trouble!
From time to time my devices with above mentioned processors corrupt content of internal program memory. Does anyone see this behavior od 80C51ED2?

that if you use RC reset (which do not hold the uC in reset during power down) your chip will occasionally lose its flash contents.

install a proper reset chip
How would that fix the OP's problem?
