Car shuts off?

I got in my vehicle after 8 hours.
I cranked the car and allowed it to run for 5 minutes. Then I drove off. It shut off once and then I cut it back on and proceeded home. The instrument panel and headlights were flickering. When I pressed the accelerator, it would be fine. When I didn’t have it pressed like at a light the truck just completely shutter off! The horn or lights don’t even work. No door chime.
