Car periodically stalls on accelerating from a stop, even though engine is up to normal operating temperature. car will get to approx 10-15 mph, then stall, with a complete loss of power. must push gas pedal all the way to the floor to overcome the stall, then the car leaps forward, spinning the tires. this has happened several times in the past few weeks. am very concerned whenever i start up at an intersection, as i don't know when this situation will occur. i think this is a safety issue which should be corrected. *tr
