My Truck starts and runs but when it gets warmed up the engine starts missing and it dies. Then when you try to restart it will not start it acts like it is floated out, until you let it set then it will start and run and do the process all over again. We do not have any error codes in the ECM and we replaced the ECM with a new one thinking the computer could be bad but it still does it.
