Advice on car problem
I have a 2001 Nissan Sentra with 27K miles on it. Today, when driving at 60 mph on an interstate the engine simply stopped and the 'service engine soon' sign came up. I pulled over to the shoulder, turned the keys off and tried starting the car again. The engine did not switch on despite several attempts. After about 15 minutes, I tried again and the engine took off. I could drive the car at about 60 mph but felt an unusal drag/effort in having to drive at that speed. I drove for about 6 miles and the engine died again. Again, I couldn't start it immediately but could start it after a 10-minute break. After this episode repeated itself 3-4 times, I reached home.
I just filled gas a couple of days ago so lack of fuel can be ruled out. Whenever the engine starts, it doesn't make any unsusual sounds. The car lights/AC etc are fine. I don't think the the car is over heated becasue the temperature level on the panel is normal. I have been servicing it regularly and the car is not due for the next service until it hits 29000 miles. Any idea what might be wrong with the car?
