Where is the PCM and the ICM on a 2008 Buick Lucerne V6.

What is your question?

Car stops running.Sometimes at idle, sometimes at 70 mph. No hesitation. Just stops running. In 5 or 10 minutes, if you are still alive. It will restart. Codes are P0606, P0601 and U0107 Then 5 to 10 minutes later it will shut off again. At idle or at 70. ( no crank condition when it shuts off, but lights, windows etc still work fine) Extremely dangerous, should be a recall or at least a TSB. Thanks

Happens more often, didn't happen for the first 66k miles. Has 67k miles now
