It hasn't happened for a while. But now it started acting up again.

The truck would completely shut off. Dash lights come on. I noticed it's mostly when taking off like from a light of stop sign.

There's no codes ever. Sometimes it will get a bit hesitant or stutter a bit even when idling and sometimes while driving.

I've already changed the fuel pump, cleaned the iac, air filter, and intake.

In my opinion the truck idles very low. Sometimes AT or barely over the 500rpm line. Like it barely wants to move when I let go of the brake. Not sure if it's normal for explorer/sport tracs.
