    I think Max Power has a Min Power problem.

    The 12F615 requires a minimum of 4.5V to do a "Bulk Erase".

    melabs programmers have a "Low Voltage Erase" option that can "Row Erase" at lower voltages.
    I'm not sure if you can do that with Microchip programmers.

    If possible, power your circuit with 5V during programming.

    The problem you thought you were having with ICSP pins in output mode only affects chips with MCLR disabled. You have MCLR enabled.
