Truck going dead when I stop. electrical?
I just checked my check engine light last week and it was a cam positioning senor code, that was the only code that it was throwing so today I replaced it alone with a new set of headlights and a new touch screen radio. tonight on my way to work when i got to a red light the truck cut off with me... then again three more times (as i come to a stop) i have a ton of random codes like; restraint system fault, seat track positioning, low battery voltage and a few other out of the blue codes. im assuming i wired something wrong but i was careful and cautions of all i did and thought it was all done right but does any one have any ideas to what it may be? im not an electrical guy but im gonna start with my lights. I connected my halo and leds that are in the headlight by using a quick connect on the running lights wiring..

Put the OEM headlights back in and see what happens. Our trucks are VERY finicky when it comes to LEDs.

If that doesn't work, leave the OEM headlights in and switch the radio back too. Gotta narrow down if you caused this or if it's something else

What will your truck do when your cam phaser is bad? i was told it may be the problem. It does tick but i have had 3 of these trucks and everyone of them has. it runs great no issues at all but when i slow up to stop, right before i stop it will idle down to 300-500 rpm and then cut off. ill throw it in neutral crank it, give it a little gas throw it in drive and take off again. some times it don't cut off but when i go to take off it takes a second for it to (build up) then go. I took my radio and wiring harness out so that eliminates that issue. i made sure my lights were wired in correctly and cleaned off my battery terminals fired it up and drove it from my garage to the front of the house 50 yards... check engine light was off of course so i let it run for about 5 min. it didnt idle down or cut off so i turned my heat wide open and my lights on and it did fine. later on my way to work about 5 min from my house my check engine light came on and then it starts cutting off every time id stop about 30 miles from my house. like i said it runs and drives great no other issues my lights stay on they don't seem to get dim or go out......

Sounds like a bad alternator to me. Better get to an autozone and have your charging system and battery checked for free. A weak alternator can give a lot of weird symptoms, not the least of which is having the vehicle die when stopping.

You need special equipment they test your battery under load and also your charging system. Autozone used to do it for free not sure if they still do. A multimeter is good for a quick check but not as accurate as load testing.
