mine was kind of doing the same thing yours was i would be driving and the car would lose power and sputter and everything and just die. turns out themain power wire on my alti was loose and caused arcking and melted the wire to the terminal on the alti. in turn it caused a fire under the hood (very scary). i had a volt gauge in the cabin when all this was happening and my volts would go from 12,8,9,10,12 it was just all over the place.
