no, it won't stop working all together if you melt the 12V. i had a board with 4x 6990 that i ran for several months with a melted 12V. very unsafe, but the point is it will still run. that board did exactly what you are describing though, it would reboot or power off under heavy load.
no, you do not need a bigger power supply -- you simply need to supply more power to the pci bus. if your motherboard does not have any molex connectors on the board to supply extra power to the pci slots, then you can get something like the EVGA Power Boost cable, or solder a molex connector directly onto the GPU.
