Hello,

2 times in the past 2 months my car engine just stopped. The first time it was at an intersection. Tonight it was on the highway. I tried to restart the car and it will crank but no turn over. I wait about 10 minutes and it will start again. After the first incident I took it to a mechanic and he said he wasn't sure what the issue was but replaced the fuel pump relay. Tonight on the highway was in a really bad area to have it die so I'd like to know what to do. Any thoughts?

I had a similar issue in my old CLS6 & it ended up being an engine ground. Really easy fix & worth trying out.

Unbolt the ground, clean up the contact point with sandpaper & repeat for all 4 grounds.

teh CL, were there any symptoms the car had that went away after you cleaned the ground contacts? Aside from the obvious "it used to shut down randomly" haha.
Mine won't start sometimes, and it seems like an issue with dirty fuel injectors (revving while cranking, and then holding at 2k rpm for 30 seconds will get the car to idle properly and not die), but I want to know if this is something I should check as well.

Except for the randomly shutting off, nada.

You might as well try freshening up the grounds, they can really mess with a car if they're not perfect.

Could also symptoms of a failing fuel pump or dirty injectors like you said.

the last time my car 'just died' on the freeway, it was because of some corroded positive battery terminals. It ate through the terminal and it was just loose. Replaced the terminal and was good to go.

I'm thinking the issue due to a faulty circuit or soldering as the system starts up after it has cooled down.

Yikes
