2003 NISSAN ALTIMA

This is the 3rd time that my 2003 Nissan Altima shuts off completely as i a driving down the street at a speed of about 40-45 mph without any notice whatsoever. The 1st time this occurred was april 29th. I took the car into the dealer and they were not able to find anything wrong with the car. The dealer performed a diagnostic caled P0725 and P1229 and called the Nissan tech line but still had no such luck. I am extremely concerned as i have had my 7 year old child with me in the car both times. Luckily, i have not had a accident so far, but it is a very scary feeling when you are driving down the street with your child at a speed of 40-45 mph and your car just completely shuts off and all of the lights inside of your the dash of your vehicle start flashing (ie. Service engine, oil, gas, lights, etc. *ak
