Our DTS sometimes starts missing, stalls or shuts down when driving. It always starts right back up. Have taken it to the dealer several times; they replaced sensors, Cat. converter (twice), fuel filters and a few other things to no avail. At a great cost to us, I might add. Need help, this has been going on for a year now!
With all the electronic's on your vehicle this type problem is hard to diagnose. It would be better if it died an didn't start back up , then it could be diagnosed . Your vehicle has a number of electronic control module's , sensor's etc..... Plus the modules all share information on a serial data bus ,communication network . A loose connection ,a module not sending info. ,anything like this could bring down the data bus an cause it to die. I feel for you , the dealer shouldn't have just replaced part's like that if they were not sure . Problems like this can take a long time to pin down . Hooking up testing equipment , using a 8 channel lab scope to check electical signals to an from the PCM , BCM ,data bus. Could take a lot of diagnostic time . Did you buy the vehicle new ? Get the factory Rep. involved , engineers from cadillac etc. When i have a problem vehicle at the dealer that's what i do , call tech help line .
SOURCE: Serpentine Belt Replacement
serpentine belts should be replaced when cracks are running across"v" portions of belt,when missing ribs 1/2 " or longer,or cracks running parallel to "v" portion of belt. the thermostat should be replaced if the car seems to take a long time to warm up or if the engine runs hot
SOURCE: takes forever to pick up speed i replaced the cat converter
I would start with a cylinder compression test and then check the timing. I'm sure the car has over 100k, so it wasn't a waist to change the cat the fuel filter. There is no one answer for your problem. Things to check or proof out, vacuum leaks, fuel pressure, last COMPLETE tune-up, EGR, MAP, ECT sensor and the E-VAP system.

so ? you know the head gasket is blown so???
i dont git it!!
you car is doing this due to the gasses making there way into the coolant and vaper locking it.
SOURCE: 2001 dts stalls 10 minutes after every startup
Its possible you have a bad connection somewhere that heats up and causes a current drop. Also if you know what system is shutting down alot of times a relay can do this. Try switching relays. What would shut a car down is ECM/ Ignition or fuel pump relay. If you have others that are the same switch them.
SOURCE: I have a 2002 Cadillac DTS. It randomly dies when
Had same problem,called my Cadillac buddy and he said pick up both crankshaft position sensors.Charged me $100 cash and has not stalled again,drove me nuts for two years.
