My TR just randomly stops and then wont start again until the next morning. We can drive it for ten minutes to an hour, but it's guaranteed to just give up and stop working for ~12 hours.

I'm not sure why it does it. At first it seemed like it did it on hills, then it seemed like it did it when the engine heated up, but I have no idea.

I checked the diagnostic codes and got crank Angle Sensor and Knock Sensor errors (22, 31).

It feels like an electrical problem, but I'm not really sure. The battery's less than three months old.

sounds like crank sensor . have you tried playing with the dizzy connection when it stops
