ok so i have a 1999 dodge ram 1500 4x4 with the 5.2 v8. so here is my problem i will just be driving down the road and then my truck will just die no brakes no stearing but my radio is still on i pulll over put it in park and it starts right back up and runs fine. it doesnt do this all the time just once and a while .....iv changed plugs wires and fuel pump im guessing its gonna be the coil but i figured i would get on here and ask.

 

sounds like coil to me

 

welcome to df.
do you have a check engine light or any codes?

does it die at high rpm/speed, or only when you let off the gas and expect it to idle.
if it dies at idle, replace TPS or IAC

if it dies going down the road at speed, maybe coil. its a cheap part, so it might be worth guessing at. if its not that, it might be worth have a mechanic do a real time scan to see if something flakey will show up.

 

I had similar situation recently where mine would die shortly after you start it when it was cold.
Then it would restart and I could go wherever I wanted, as far as I wanted, shut it down as many times as I wanted so long as it didn’t get completely cold again.
I had replaced a damaged crank sensor (damaged during transmission install) with a Napa crank sensor.
The Napa crank sensor was causing this issue.
Replaced the Napa sensor with OEM and issue was gone.
Never got any codes the entire time this was happening.

2 points to all this:
1) Could be crank sensor causing this.
2) Only use OEM crank and cam sensor when replacing them.
