Won’t idle on start up when cold

97 Dakota 3.9, manual trans, 4x4. Truck will start
but not stay running when it’s cold outside unless I
hold the pedal for a few minutes. If it’s warm
outside or after the truck warms up it runs fine. I’ve
changed the idle control valve cleaned the throttle
body. And changed the throttle position sensor.
Also sometimes when it stalls on cold startup the
radio will reset like the abattery was disconnected
not sure what’s going on.
