Engine Stalls

My chrysler 300 m keeps dieing out while driving. It dies out while going any speed. I had a mechanic put on machine and he cant find anything wrong. I have stopped driving it because I have almost been in 3 accidents while going 45 miles per hour and it stops running. The battery is fine and I dont lose electric but the engine dies. When it dies the cruise control light comes on the dash and I never use cruise. What is wrong with it?

I have a code reader that says po340. So, I have changed cam and crank sensors. Still, the engine will not start and I have no headlights. Also, I removed the large ground wire, the one with 4 leads, which was greasy, and cleaned that. Thank you very much for any help.

Hi KHLow2008, Yes, I have checked both fuse panels repeatedly. Have even swapped the ACD relay fuse with the other identical one. But, same result.

Thank you. No I have not checked for sparks or f. Pressure. I will check your link. Thank you again.

Have also checked and re-checked both fuse panels. I can hear the humm of the fuel pump when I turn the key. Thank you very much for any help.

By the way, when I try to donate, a screen pops up that your site is not using a trusted certificate. Says that someone is tampering with the connection. Should I mail a donation?

Thanks again. James

The links/videos are great, but, I think if I can source the headlight issue, I will find the engine issue. I remembered also, that I had a coolant leak in the middle of the front of the engine. I guess another water pump is in order. After I get it running of course. Radiator was new 12 months ago. Starter is new 2 months ago. Water pump 24 months. Thank you again.

Um, I mis-stated the starter thing. The battery was new 2 months ago. My bad.

Changed the battery today 1000 cca, alarm went off briefly, then when you start the car, it runs for 7 or 8 seconds and then shuts off, if you start it again, it runs for 7 or 8 seconds and the shuts off, you can hear the fuel pump go on, etc, for the few seconds the car runs, if you touch the gas, it will die quickly, it ran fine before the battery change, now this, when it is running for those few seconds, it runs normal, no rufness or anything

I can stop the stalls, I just have to keep my rpm gauge up and not let it drop to 0, I learned to deal with it for a while till I could get money to fix it, but then my car started shaking very rough. I spent 250 to get a fuel injector flush and after a day of smooth running, the problem came back worse. I got all the usual tune ups done, and the problem persists. I read online that it might be the egr valve and when I asked the mechanics to fix it, they said it was fine. They said they need the computer code to come on before they can figure out how to fix it but I need the car to be running soon and can't seem to force the check engine light to come back on, what can I do to get some results faster.
