Maintenance/Repairs

About 2 weeks ago my 1997 Buick Park Ave (115,000 miles) began running bad during a heavy rain storm. It was running fine. Then all of a sudden at a stop light the motor hesitated and wanted to stall. I nursed the gas peddle and limped home and turned the car off. The car hesitated and sputtered all the way home as if I was running out of gas.The next day the car would not start. It turned over but would not start. I tried starting the car for three days. My mechanic friend later diagnosed the car and stated the computer was not functioning correctly. He replaced the computer. The new computer seemed to correct the problem. The car ran great for the next 2 weeks. Yesterday, it was raining hard while I drove the car about 150 miles without any problem. Then suddenly again the motor started running badly. Again, the motor wanted to stall and hesitate as if I was running out of gas. I limped home again. This morning I tried to start the car without any luck. In addition to installing a new computer, In the last 2 months I have changed all the fuel injectors and installed new spark plugs.I have also changed the fuel pump and repaired the fuel tank. My mechanic say the cam sensor and crank sensor are operating correctly. There is spark coming from the coil packs and to the spark plugs. Can you offer some suggestions so I do not have to randomly change parts.
