Hello and thank you for using Just AnswerI'm Paul and I will help you with your Question
a crankshaft position sensor is a common failure that can cause it to die while driving
when it dies did you notice if the engine light is on? the engine light should come on when it dies because of the stalled engine... if its out there is a good chance your crankshaft position sensor is shorting out the computer
let me know if you are loosing RPM signal when this happens and if the engine light is on or off.
does it restart right away?
I would suspect the crankshaft position sensor
it is a very common failure
and it would cause it to be hard starting once it happens until letting it cool down
they tend to fail when they warm up
I would change the crankshaft sensor
Most of the other problems that cause stalling only cause stalling at idle speeds
the crankshaft sensor is the only one I can think of that causes stalling while driving or at idle speeds.
I will see if any other experts have any ideas for you
Hello and welcome to Just Answer!
Lets try this - Sit in the vehicle with all doors closed and starting with the key in the off position, turn it to ON, OFF, ON, OFF, ON (don't turn the key to the start position just on) within 5 seconds and leave the key on and watch the digital odometer to see if it displays a fault code. It will be a P followed by 4 numbers example P0700. When it is done displaying codes or if there are no codes it will say done. If you can't get this to work, please try it again following the instructions!
That's strange! If the check engine light was on with the engine running, it should have a fault code stored and it doesn't.
When it dies will it start right back up or do you have to leave the truck sit awhile before it starts?
When it dies, does it die at highway speed, slow speed driving, coming to a stop or any of these driving conditions?
Did this problem start all of a sudden or did it gradually get worse?
This is going to be very hard for me to diagnose when there aren't any codes coming up.
I don't want to give you a guess or waste anymore of your time, so i will opt out and see if anyone else has an ideas for you.
Sorry I could help, good luck!
