I have a 2002 Town/Country. I started the vehicle, the power steering felt tight. I drove a short distance, turned off the vehicle about 5 min. Started again and began to drive steering okay. About 4 miles later the engine shut down. I was going about 35 mph. Coasted to a stop. Tried to start it again. Would not turn over. Lights and accessories opperational, no engine start. What’s wrong? I have since put a new battery in and starter relay. Dash has indicator light lite, a red dot. Anti theft, I’m thinking. Can anyone help?
