Try cleaning the throttle body, many cars will have trouble staying running if the battery is disconnected unless the throttle body is cleaned to remove the accumulated dirt buildup that the computer doesn't know is there anymore once the battery is disconnected.

FFT (Food For Thought) ...

After replacing the battery did you reset the BMS (Battery Management System)? If not, and the reason for replacing the battery was low voltage and/or poor performance, you may be experiencing a perceived low voltage situation.
Battery Management System - reset

(Reader's Digest version)
  • have dealership reset BMS.
    -or-
  • after installing battery, leave vehicle alone for 8 hours.
Perfroming a BMS reset will reset the battery SOC to a default of 85%- regardless of its true state of charge and reset the SOC drain timers. This should get you out of load shed. The following is the procedure using the Diagnostic Engineering tool.

BMS reset procedure with Ford "Diagnostic Engineering Tool":
Go to Gen Diagnostics and select Module ID to 726 (BCM)
Select Service 0X10 and extendedDiagnosticSession, and press "Send Message" button
Select Service 0X31
Check "User Defined" box, and type in "201A"
Press "Send Message" button

For all future reference, do not connect the negative charge lead to the negative battery post. Connect it to another ground attachment point on the truck. That way, the re-charge will be measured by the BMS hall sensor (very near the negative battery post) and will correctly re-adjust the battery SOC.

If the dealer plays dumb, here is the section in the workshop manual:

When charging the vehicle battery by connecting the charger to the negative battery terminal is necessary, such as when using a combination battery charger and battery tester/analyzer, like the GR 1 190 V3.0 Intelligent Diagnostic Charger, the BCM will not immediately update the battery state of charge. In this instance, after charging, you must carry out the Battery Monitoring System (BMS) Reset using the scan tool. This reset is needed for proper engine off load shedding and to prevent invoking of engine off load shedding earlier than normal.
NOTE: If the reset is not carried out, when the battery is charged by connecting the charger to the negative battery terminal, it takes approximately 8 hours for the BCM to learn the new battery state of charge. During this 8 hour period, the vehicle must be undisturbed, with no doors opened or keyless entry button presses. If the vehicle is used before the BCM is allowed to learn the new battery state of charge, engine off load shedding can still occur and a message may be displayed.
When charging the vehicle battery by connecting the charger to engine or chassis ground, the negative charger clamp must be connected to an unpainted chassis surface or a solid engine component such as a generator mount or engine lifting eye. In this instance, after charging, the BMS Reset is not required. Through this method of charging the BCM will update the battery state of charge during the charging process.

All you have to do is let the truck relearn the idle values. That's why it stalls when you hit the gas. Disconnect the battery again then reconnected then start the truck and let it run for five minutes in the driveway in park.
