Its not possible to resume a print that fail halfway unless you know how to manipulate the gcode of the file.
I have problems like this before and it depends on a few factors.
You might want to check your power supply and the cable.connecting to the printer, I had a problem once where the power supply shorted internally and had to open the sealed laptop case to fix the problem. Another is to see if any of the power supply wire is melting. I had a power supply wire barrel plug melted a little and the wires inside was slightly burnt.
Another issue is due to the usb communication, make sure to use a cable as short as possible to avoid any data loss. USB supplies 5 volts so their voltage drop a tremendously over long distance. A 1 meter cable will have more data loss than a 10 cm cable. Also winding a long cable around a ferrite core helps in reducing noise.
Also, if you think your house have electrical issues, you might want to invest in a uninterruptable power supply, UPS unit. At least the backup battery will sort out any micro power interruptions and also keep your printed running during a black out.
Thanks for the insight bro altan.
Hmmm... You suggest that it might be a problem with the power supply? Guess i will need to do something about that soon. If you are right then that should also explain the mysterious problem i have with my overheating mosfet. Never knew that a long usb cable will be an issue too. Time for me to switch back to the stock short cable.

By the way, my lcd controller just came in today. Can i just plug it in and use it straight away?
Thanks again guys!
