Radio Cutting, GPS Cutting, Stalled Starts

[Alvinvannoy]

For the past couple of days I noticed that my Range Rover has hesitation or stalls when I attempt to start it. When I am driving, the radio and GPS will blink off and pop back on. The "Gear Box Fault" message has come on. The symptoms read I need a knew alternator.

Any ideas of what my problem maybe?
