Crankshaft Position Sensor problems of the 1996 Jeep Cherokee

While leaving home from work, the vehicle started to shutter and fail. I managed to get home at a speed of 40mph since I noticed that at a higher speed, the vehicle would try to stall. The next day I tried to turn on the vehicle but it would not turn on. I called a certified mechanic and received instructions thru cell phone to shake a bit the cables to computer components and cables to distributor components. The vehicle turned on but with problems. I managed to drive to mechanic shop where the Cherokee was left for testing and repairs. The diagnostics showed a faulty computer. The computer was replaced. About three months later, the vehicle stalled again at a cross road and turned off. A truck nearly struck me because I couldn't get out on time. The mechanic had to show up at the site and had some problems starting the Cherokee. The diagnostics, another blown computer. The mechanic ordered another computer with upgrade (had to wait about a month) original crank shaft sensor was added. All seemed to work well until yesterday oct/2/2013 when I went out for a ride with my son and the Cherokee stalled and turned off. The same symptoms as before. I have spent about $1,000. 00 trying to get my Jeep Cherokee to run properly and now I'm afraid to take it out to the street. I have a family of 4 and I worry that the Cherokee would fail me by stalling again at a crossroad causing a fatal accident to me or my family because of this electrical failure. All cables were checked for shorts but nothing solves the problem. I did some recall search but nothing official although some Jeep grand Cherokee users report the same problems for their 4. 0l engine (my Jeep Cherokee is also 4. 0l) coincidence? I love my Cherokee but feel that I can't rely anymore on it as for safety. Had it for about 6 years without problems the first 5 years.

While driving at aprox. 40-45 mph, the Jeep would start to shudder. Eventually it would shut off. The Jeep would then crank but not start. I had this problem happen for about four times. Three of the times the Jeep was towed to a repair shop. Twice the pcm unit was replaced and twice the crank position sensor was also replaced. The last repair was 1 month and a half ago. Two days ago, the Jeep stalled again down the road. I was traveling with my wife and children. We almost lost our lives. A 16 wheeler almost collided with us due that I could barely manipulate the Jeep because it turned off on me. I tried to do some visual inspections under the hood. I had one of my sons to wiggle the pcm (computer) while I cranked the starting switch. At one point the Jeep managed to start again. Then it stalled the moment my son stopped wiggling the pcm. I had another tow truck pick up the Jeep and send it back to the mechanic. Chrysler has not corrected this issue on the pcm and perhaps might not do it until one day someone gets seriously hurt. Videos on youtube show other Jeep Cherokee owners having the same problem 1996-2001.
