Just be glad that your sensor did not fail 10 hours from home as mine did. Don't be surprised to find that it will take several days for your garage to get you a new one. The symptoms that you are describing are classic for this failure. Let it sit for an hour and you might get another 30 minutes down the road. But the time to failure will get shorter until it goes completely stupid. I just replaced the CPS and not the Cam sensor. Things have been fine since.

There are those that will tell you to put together a small stash of parts if you intend to get far from home. On all of those lists you will find a CPS.

Good Luck.
