1995 Jaguar XJ6 engine dies when coming to a stop and transmission warning light comes on and transmission will stay in third gear and not shift out. The battery is less than a year old and checks out?

I had this issue and I finally traced it to the crankshaft position sensor (CKPS). If the CKPS gives erratic information to the ecu the ecu puts the transmission in limp home mode. Eventually the CKPS will give up entirely and you will have a no start situation because the ecu does not have a clue what position the crankshaft is in so does not know when or what plug to fire.

Also engine dying when coming to a stop could be causedby a dirty/failed egr valve though this will not put transmission in limphome mode. Both these possibilities should throw a code. Get the OBD11 code pulled and you will be pointed to the right direction.
