Returning from Church this morning the dash lights, radio and A/C fan cut out 4 times in about 30 seconds.
This time I noticed the speedometer dropped to "0" also during those times.
Even though we were going about 35mph the needle of the speedometer to "0" and returned to 35.
Once while we were at a stop light, it all went dead for a split second, but the engine never stopped or burped.

Does this help identify a gremlin or bad sensor?
