What are the ratings of the power supply you are using? I had the same problem that you are describing and had to upgrade from a 600mAh power supply to a 1000mAh or 1A power supply. After doing so fixed my problem. The current retropie image increases the voltage by +2 and sets the overclocking to a medium setting by default, which requires more available power.
