I have to be honest, I can't see why they would shut the engine down. I think there is a wiring issue. Something may have been knocked loose or damaged.

Hi I have a 2006 Dodge Charger R/T 5.7. The car keeps stalling on me. When the car is cold I can drive it all over until it reaches operating temp, then it stalls. There was a p1521 code so I changed oil and cleared. Now there is a P0300 multiple misfire. I have replaced fuel pumps, Crank sensor, Cam sensor, Plugs, Air filter and ECT sensor. Before the car stalls the ETC light flashes and stability light is solid. If I let the car cool down it will start and run again til it is warm. Please help where do I go next?

Hello,

This sounds like the ASD relay is getting hot and shutting down the engine here is a guide to help you confirm the issue and the engine wiring diagrams so you can see how the system works along with the ASD relay locations.

I have checked fuel pressure readings are normal 59psi. Fuel pressure regulator and filter are on the new fuel pumps. All coils are firing as they are supposed to be. I work at a shop and have pretty much did everything including a back pressure test. I have done a smoke test and cannot find any vac leaks. I have done everything, but flash the computer. I don't think it is a computer issue though.

Have you checked the ASD relay? I don't think it's a fuel pump issue.
