Car cuts out as it slows intermittently. Can go for 200 miles with no problem but then can cut out 3 -4 times over a 10 mile drive. Diagnostics showed cam phaze sensor which has been replaced but still fault remains. Car will normally start again if left for 4 - 5 minutes. We have a problem with the barrel in the car in that you can remove the key from the barrel and the car will continue to run. This can be done at 3 positions on the barrel. Iwasn't sure if the fault could be related to barrel affecting the immobilizer? If it is, does it mean a new barrel and will I have to go through Chrysler for this. The car is 10 years old but is in great condition, regularly serviced and going great apart from this fault. Any advice would be appreciated.
