Anti-theft Controller problems of the 2001 Ford Explorer Sport

First incident occurred on 09/11/2003. The vehicle would start and drive fine and then after a number of stops, would fail to restart. I took the vehicle into lithia Ford in fresno. The vehilce was in their service department for 7 days before they could determine that it was a failure with the "pats" system. A Ford factory anti-theft system that does not allow the vehicle to start. Per the Ford service flash test, "code# u1262-inter mitten loss of scp communication. This repair cost me 3 x $90. 00 for their diagnosis = $270. 00 + $86. 58 (part) = $357. 00. The whole week of July 12, 2004, the vehilce would not start with the same problem as 09/2003. I phoned the dealer again and they asked me to bring the vehicle in. Lithia Ford of fresno had the vehicle til August 11, 2004. After charging me the $90. 00 diagnosis check, they claim "no problem found". The vehicle has had in this past months 2-4 incidents of the inter-mitten start. ** this is my third complaint to the dealer of the same "non-start" problem. This morning I was at lithia Ford, when the vehicle would not start in their service bay. I was given another $95. 00 diagnosis estimate, and they state they need a couple of days inspect car. I had to rent a car at $30. 00+/per day. Please investigate this factory "anti theft" system. I need a vehicle that will start.
