Car stalls while driving

My car stalled while driving 70 mph on the interestate and stalled once when driving 25 mph on a slight incline on a city street. there is a NHTSA recall for 2008 Chrysler Sebrings that says a short in the Tire Pressure Monitor Sensor can short and cause this car to stall. The dealer says they checked this and this was not the problem. What do I do? Sell the car? That would be better than dying because it stalled in front of a truck at 75 mph!
