The electronics inside the car went dead while driving but not the engine. on 1998 Nissan Maxima

It happened a few times. It seems like the ignition may be loose. The dealer hooked up the computer but nothing came up. Any ideas??

you either have a bad ground or the circuit board on the back of the cluster it shorting out
possible electric malfunction
IF you wiggle the ignition key while it's running , can you duplicate the symptom you describe? If so , replace electrical portion(if seperate) of ignition assembly.
