2008 Sebring won't stay running
 

So my Sebring died on the highway today. It's the 2.4. the dash lights stayed on but the engine turned off. Now it'll start and stay running as long as I hold the key in the start position, but dies right after I let it return to the run position. I just changed the ignition switch (not the lock). I've tried both keys and they behave the same, and I've checked the fuses. Any ideas? Help!

Have you checked for any stored trouble codes.
With the symptoms that you describe it should have some, and they would help figure out the problem.

I have with my cheap reader. There were no codes. It seems to be a bad connector under the fuse box. When I shake it the symptoms drastically change. I took it apart and inspected everything. And also changed all the 20amp fuses. Then put it together and it seems to be fine ATM.

Starter relay ?
