93 ls400 engine / instrument cluster cut out during acceleration
I was accelerating to merge into traffic at maybe 30 mph and pressed on the pedal just a little bit to get the car up to speed. The engine and instrument cluster (lighting, needles, etc) cut off for a split second. It is almost as if someone turned the key off/on quickly. This hasn't happened before and I drove the car fairly hard with lots of accel/decel/stop/go for about 30 minutes the following day and there were no troubles.
Since the instrument cluster turned off I suspect some power or ground problem. Could an ecu issue cause the instrument cluster to turn off?
