Engine Dies while driving...No codes and starts immediately.

[Brian Savage]

'03 RAM 2500 5.7 Hemi

I was driving down a two lane road with a load of hay on the truck and pulling a trailer loaded with hay and all of the sudden, no power steering, not power brakes! The engine just died. I put it into neutral and switched the key to ACC and then started immediately. The truck did this a dozen more times before I got it home.
When it dies, it's just like someone shut the ignition off. The tach and speedo stay at where they are for about two seconds, and then they just drop to zero like someone shut the ignition off. The truck will not restart if you go right to the start position, but if you turn the key back to ACC and then to start, it starts immediately every time. What did happen at one point is the ETC light started flashing at one point right when it died. It did this two or three times and then stopped (even though the truck still died.)

I have scanned it for codes and nothing comes up. I know it's due for plugs and wires and those are ordered. I was also going to clean the throttle body, as I've seen on line that it can cause some problems.

Any other suggestions? I'm supposed to make a 600 mile trip to pick up a new horse for my daughter in a couple weeks and the last thing I want is to lose my power streering and brakes again with the horse trailer in tow.

Thanks!

Sounds as power fails too fast to write a error in the ECU.
Check your cable connections, but most likely a relay who fails and cut power to the ECU, or the ECU itself doing the same thing.
That is a nasty error to track down, best would be to swap Relays and then ECU with known good ones to check if error goes away.
Powersteering and brakes quit working because your engine dies, and if you are not absolutely sure that the error is gone i would not haul anything

Did you ever find the cause of your issue? I had a similar issue and posted it on a thread here as well: http://www.ramforum.com/threads/dealer-couldnt-fix-pcm-map-issue.118216/#post-1699538. I just dropped our truck off at a local shop who I hope will have better luck than the dealership.

Similar thing happened to me last year. Engine dies while driving. No codes came up for awhile.
Turned out to be ckp sensor

Mine did that ended up it was the thing on the steering column called velco the connection was melted and I ran my own wires to the remaing pins that weren’t burnt

Throw a fuel pressure gauge on it. See if it’s fuel related. Could be a TIPM issue too. And crank sensor

If it does this, there’s a problem.
