Hello I have a 2001 trooper with the v6 automatic it started small and slowly progressed into a problem where its not drivable when driving the motor cuts out and all the warning lights come on usually i can keep it running but not always used my obd2 reader and no codes are thrown ive tested the alternator and battery cleand battery connection ran some seafoam through the fuel not sure what else to do

 

Sounds like it might be the ECU.
