It is possible that the connection between the B+ cable and the Power Distribution Box can become damaged by wear and heat which is caused by high current flow and high contact resistance. Normally this will result in a non-start situation after parking the vehicle. However it is possible that this could in extreme cases occur whilst the vehicle is in motion. The driver should be make aware of the issue by flickering of the instrument cluster (dash) or an engine mis-fire; but if the driver does not then the engine could cut-out without warning.
