1997 Plymouth Breeze sensor, engine stall

I have a one owner 97 Plymouth Breeze purchased brand new in 97. The car has been very good to me, at nearly 300,000 miles I’ve defiantly got my 16K worth. This car has been an everyday driver from day one, it’s taken me any and everywhere I wanted to go without incident or accident. However I have made some minor repairs, other than routine upkeep including a fuel pump and TPS and an EGR I have replaced the transmission (at a little over 100K) 2 replaced timing belts and 1 new head. This car has never let me down until now. It began with the driver side CV starting to knock immediately followed by the same side ball joint breaking, witch meant replacing the whole control arm. I first thought the problem was more than I could handle and since I had other vehicles I let the Breeze sit, for about 8 mo, 6 of witch without the battery. When I finally replaced all suspension and front end components (never before replaced) I had to also replace all cooling parts because the antifreeze had broken down all plastics. After putting it back on the road it stalled that day less than 4 miles. Over the past 5 months I have gone over everything by the book, by the numbers, everything is within specification. I even replaced the computer with new, all to no avail. Why is the car stalling? I don’t want to replace sensors that don’t need or take to a shop as I prefer my own work. Where is the trouble spot?
