Probably just needs rewiring. Tungsten lights are really simple and if you open up the casing you should be able to find the weak spot in the wiring, cut it out, and attach it back up again.

use a multi meter to check continuity and resistance
start at the plug and work your way back to the head
check the plug to make sure all the wires are teminated
wires commonly break inside the insulation about 2-6 inches from the plug due to constant bending.
next check the switch for terminations that have come apart and the wires inside the insulation on either side of the switch.
if the above are ok check the housing
the most common fault i have found is wires broken inside the insulation at the point where they enter the housing.
check the termination of the wires to the lamp holder the flood/spot mechanism can cause these wires to break or come loose.
for your safety visually check the earth is terminated to the body and has uninterrupted connection to the earth on the plug
use a multimeter to check earth continuity/insulation resistance (i have said this twice because it is vital for your safety)
if you are having trouble drop it off to an electrician, he can give it a good going over and safety test for a reasonable fee.
cheers
ps. electricity has one aim in its existence. to find a path to ground.........the easiest way for it to do this is through the earth connection which is a direct connection
to the ground (literally).
if the earth line is not connected it will find another way, that is usually through your body with unpleasant results.

What everyone else said, probably bad wiring or a bad socket. Some GY9.5 sockets used in 300-650w fresnels are known to be problematic.
BUT - if you had to cancel a whole shoot because ONE light went down, that's a bigger problem. You should have some redundancy. This doesn't necessarily mean getting more units than you know you'll ever need, but have at least something mildly similar to substitute in the event of an equipment failure.
