2001
Mercury
Sable
engine 3.0
114,000 miles
Car temp gauge showed car about to run hot, stopped and added antifreeze, as it was empty. Car started stalling trying to cut off. Cut off a few times. Did pressure check and found pin holes in reservoir, Replaced reservoir. Now, temp gauge shows OK but car cuts off when it warms up, ie., sitting at a light, while driving tries to cut off. What could be the problem NOW

Could be a lot of stuff.... How does it drive off idle? If ok, you could be looking at a vacuum leak, Those were real common to have the PCV hoses split or a bunch of other stuff 
Good place to start would be take care of any maintance work that is over due, also clean the Mass air flow sensor with the correct cleaner (MAF cleaner), Fords are notorious for having bad MAFs (I know it's a Mercury) and see if any of that helps or cures your problem.....

To add - Penny:
No car like running hot. Weak links are the "secondaries" or high voltage items for ignition historically. How much coolant did you need to add to achieve full again? The base 3.0 Ford has proven pretty tough over the years but is still subject to head gasket issues and something could still be getting wet from coolant that isn't happy about that. That alone doesn't really explain it cutting out completely as mentioned.
Difficult to find out but see if you can isolate lack of fuel or spark while it's down to help direct the fix,

Each time car tries to cut off while driving "theft" light flashes. Took car to a mechanic and put on diagnostic machine, told me that there seems to b a problem with the alarm sys. But their machine could not read the code. Referred me to a dealer......What do you think?

Especially if an aftermarket anti-theft device you need to know what brand it is and who deals with them. They are frequently trouble as they age,
