    I have the same issue of the CTS stalling for no reason. I found that I had a short in the ignition key. My knee would hit the key chain dangling down and in just the right circumstances the ignition would short out and the call stall. I replaced the ignition switch and the problem was solved.

    My 2003 CTS is also stalling without warning, but also has been stuck in the crank mode sometimes when starting. I noticed from another owner that he replaced the ignition switch. This might be the fix since both could be related to the ignition switch. Does anyone have experience with this issue?

    I had that happen and had to replace a sensor located on the engine. The sensor is supposed to keep the engine from getting too hot. That's why it shuts it down. Only when the sensor isn't working correctly it shuts the engine down even when nothing is wrong. When the engine cools it starts and runs okay until the sensor decides to kick in again!! Cost me around $300 to replace the sensor.

I had a similar problem the car would start fine then when driving it would just stop - if i waited long enough it would restart just fine and the same thing would happen. I replaced the crank sensor and the cars been running fine ever since. Even though the sensor ohmed good when cool???

Have a 2003 cadillac cts my car will crank but not turn on some times it will start but i will be driving and get to a red light and it will completly shut down on me it does not always do this at times it...

how many miles are on your car ? will it start up after it shuts down or do you have to wait 20 or 30 min. had a problem like this with my own car it had 1600,000 miles on it. do you have any warning light on dash when this happen, if not, it's most likley it is the crank position sensor. it's about $60.00 at the dealership, not fun to put in. also could be a fuel pump problem, have a pressure test done on pump first before you buy a pump it is about $400.00 + $600.00 to put in. I haven't seen to many pump problems without a lot of other issue while driving. If warning light are on, have the computer scanned first.

good luck bro,
i have done many CTS's like this and all turned out be the sensor.

If You Have Access To A Scan Tool, Check For DTC P0335, If It Does Even As History, Replace The CKP Sensor First.
