is this a super coupe? does the speedometer also drop to zero when this happens?if so id suspect a bad ground, or an ignition switch going bad. if only the tach drops id suspect the crank sensor. they are notorious for going bad on the supercoupes. make sure that the crank pulley is not wobbling erratically though, because if it is,it is a sure sign of the harmonic balancer about to fail, which can also cause your symptoms.Again all the info i have given you is for the super coupe, so if you can be specific about your model and year, you might get some more help.
