D1 stalls in heat

[robert freye]

hello all on my way home last night sitting at light and truck dyed, waited for about 15 minutes and truck started up and got home. vehicle has under a 1/4 tank of fuel, and outside temp about 70 degrees yesterday. i know the fuel pump relay box, the black box under hood is new from dealership, i know the crankshaft sensor is new too. for right now ill just keep the gas over half a tank or keep the truck full on gas. iam thinking its heat related, iam at a lose of ideas

D1's eat fuel pumps. Mine simply wouldn't start one morning. I swapped the pump in the driveway and it was good.

If you don't recall when it was replaced last, I'd start there.

A battery test wouldn't hurt, either.
