1995 Dodge Intrepid

I have a 1995 Dodge Intrepid 3.3L. It has 194k miles on it but has been a great car giving no problems until recently. The starter went and I put a rebuilt starter on it. Shortly after that (and it may not be related) the car would not start after it was run for awhile. It would cool off then would start right up. At first it would do this after the car had been run for quite awhile but now it won't start after the car has been run only 10 miles. It cools off and starts up. It also shut off and at a stop sign recently and wouldn't start. I took it to the garage and they changed a "module" but that didn't help. Any ideas?
