Truck won't stay running
I have a 03 Dodge Ram 1500 4.7. Driving down road at
35-40 mph the truck will shut off. You have to turn switch
off and crank it back up an it will run again until you go
35-40 mph. What causes this?(I have changed and check
oil, changed transmission fuild an filters, replaced
pressure sensor on transmission, replaced throttle flow
sensor and changed gas cap and cleaned 02 sensors)
