No.
It is perfectly possible for electricity to flow even at absolute zero - those who think it is not need to revisit their understanding of what thermodynamic temperature is.
Superconductivity is a very special case, and you cannot form electrical impulses in a superconductor - in fact you cannot change the current flowing in a superconducting circuit at all without introducing a non-superconducting element (usually called a weak link).

An electrical potential is uneffected by temperature. It is only the transport meduim that is affected, which changes impedence/resistance values of the material. As relates to Super-Conductors the colder an object the closer the atomic bonds hence the reduction of resistance, heat is energy and causes the atomic bonds to become further apart causing resistance.

No. In fact, the opposite is true. As temperatures drop, electrical impulses are transfered more rapidly and with greater effectiveness. This is the science of "Superconductivity."

Well at absolute zero, no electrons will flow.
