So my truck sat for just a day and when I came out the next day to crank it up it just started to sputter like it was missing or not getting fuel. It finally started to idle correctly. I went to the gas station to fill up and when left it started fine, however I drove a mile or two and stopped at a light and the truck just completly stalled. I put it in park and started it again and it cranked right up. I have no clue where to really start....fuel filter? throttle body? or something worse? Any leads would greatly be appreciated. Thanks.
