I have a '97 Intrepid with 70,000 miles. It ran really well until last week.
The temperature was 30F in the morning when I started the car. I drove for
about 45 minutes of highway and local driving and parked the car outside for
2 hours. It had warmed up to 50F. I started the car and drove about 1 mile
and the engine stopped when I stopped for a traffic signal. It immediately
started and ran well.

I drove it for about 30 more minutes and then parked it for a few hours. I
started it and drove for about 30 minutes with no sign of hesitation or
stalling and parked it for a few hours. I started it again and drove 2 miles
and got on the interstate. I was driving at highway speed for about 3 miles
and the engine stopped. There was 3/4 of a tank of gas at that time. I
coasted off to the shoulder and it cranked normally and would not start.
There was a lot of road noise so I couldn't hear if the fuel pump was
running when I turned the key on. I tried to start it about every 10 minutes
until the tow truck came (45 minutes). It only needed to be towed about 5
miles to a local garage and started immediately after the tow truck dropped
it off. They have checked that all readings are normal and there are no
engine codes. They have taken it for test rides and probed the wiring and
the car runs perfectly.

So now I have a car that is not dependable. Any suggestions?
