My truck completely shuts off while driving long distances on the freeway at speeds greater than 60 mph and then slowing down in stop and go traffic. it also falls dead on local roads at 30-40 mph. i can literally press the gas pedal to the floor and with no pressure to the accelerator. there are no warning codes or alerts when this happens. i took my vehicle to the southwest infiniti paid for unnecessary service and the problem still remains. i am able to restart the vehicle;but from only park or neutral. i then have to rev up the engine for at least 5 mins before i am able to get any type of acceleration. this is very dangerous and i almost got hit several times.
