You should be able to power the PIC with the PICKit3. Look at the pin outs for the PIC16F628A and connect them to the corresponding pins on the PICKit3 and you should be good to go, as long as the PICKit3 is connected and is Powering the PIC. If you need to run the PIC with the PICKit3 disconnected, you will have to then provide external power and also hold MCR high, refer again to the PIC PDF.
