Question about Ford Freestar
Unless the onboard computer is giving you a Code for the crankshaft sensor every time, I would look for another reason. The crankshaft sensor does regulate the fuel pressure by reporting the RPM to the Brain and it then gives you the fuel you need for a given RPM. If there is a problem with loose wiring or if the Brain is not handling the report from the crankshaft sensor you would have those problems.
As for the Mechanic, could be where he drives it, compared to where it stalls for you. There is a Dealer machine which attaches to your vehicle and it does many more tests than the
onboard computer or even some handheld scanners.
I believe it was once called an Odessey" machine by some makers.

Try changing the throttle body position sensor, or the ideling screw. , Service the fuel injection system (injectors and filter) have the gas tank washed as there could be rust paricles in it. and if that fails you will need to have an engine job done. Chances are the pistons are worn out or the rings are bad.
Other possible causes are the torque converter or the transmission itself, However if it coccurs with the ac, it means that it happens when extra stress is on the engine. This is caused by eighter the fuel system or the engine itself.

Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

A late reply; I'm sure you have found the problem by now-
It sounds as if the battery (old and new) are not receiving sufficient charge.
Check the drive belt tension and add a cheap digital multimeter to your 'tools.' These can be had for well under $20 US and you can then check across the battery terminals to see if the charge voltage is between ~ 13-14.3 volts at an idle. In no case should it be lower than 13 volts with the engine running since the nominal battery voltage is 12.6 volts when fully charged.
You may have a separate regulator that is ill.

Check the battery. If the battery is weak all you will hear is the starter soliniod clicking. Make sure that all of the cables have good clean tight connections.
Most Auto parts stores can test your battery to see what shape it is in.
