The most common issue for this scenario will be the crankshaft position sensor. It is mounted in the back of the engine near the firewall. The best test is ice water. When the car dies pour a glass of ice water down the back of the engine on the right side (when facing engine) and if the car restarts the crank sensor is the issue. Hope this information helps , happy new year! Please take a second and click the stars at the top of the screen to rate my service so I may receive my credit for helping, 5 STARS is ideal. Please request me in the future! Keep in mind that when you rate it does NOT end our conversation, you can still return here to me for follow up information if needed just simply reply back, THANKS!
