Started this week, when driving (highway or around town & any time of day) engine just dies.Has happened maybe 2-3 times each day randomly. Happens sometimes after a cold start or after driving for 45 min. All power stays on, almost like fuel is just cut off. Have been able to coast to a stop, put back in park and restart each time. A couple of times it did not restart right away, took several tries. Other than this everything runs great. Checked for codes but got nothing?

Thoughts? Fuel, Electrical???
Any ideas how to troubleshoot further?

thanks,

Make sure that you have fuel pressure at the fuel rail with a mechanical pressure gauge. Also make sure that you have a nice blue spark. But the problem does sould like you CPS is going out.
