First of all hi, long time listener first time caller.

So I've had my 2004 Ram SLT Hemi 5.7L since 2004. For the first 50,000 miles there were about 4-5 times I can recall experiencing the "slow stall", where the engine basically shuts down as though a light switch was flipped to turn it off. All of the sudden though it's happened 4 times in the last 4 months. You can look here to see some other examples of the issue.

Here are the symptoms (which I think are pretty well known to members of this forum by now)

1. No check engine light.
2. No codes.
3. Typically starts right back up.
4. When it happens it (to the best of my recollection anyway) happens right after I fill up the tank from empty. (I think this is a key symptom).
5. It doesn't always happen when I fill up the tank (as evidenced by the infrequent occurrence).
6. When it happens it is when I hit the brakes hard at a slow speed to taking a sharp turn at a slow speed.

It is very unsafe because I lose all brakes and steering. The worst instance was a few days ago as I was merging onto the interstate during morning rush hour. This was also the first time that the truck didn't immediately start back up, which concerns me even more. I would normally just throw it into N and start it up but ended up having to go into park and turning it over 4-5 times before it finally started.

I've gone to the dealer and had them flash the PCM and brought the TSP to their attention. That was a couple months ago and today is the first time it stalled again.

Has this issue ever been definitively resolved? I think the fact that it happens right after filling up the gas tank has to be a huge clue but I can't figure out what it's telling me.

I've got to figure this out because it's very unsafe and I'm losing faith in this truck now. Ideas? Soultions?
Thanks!

the dash go dead ( all the gauges just drop out) and does the odometer read bus sometimes when it happends?
Nope. Everything is on and running when it dies. In fact sometimes I'll have the radio up too loud and won't even know it died at all until I try to turn the wheel or break. Pretty scary.

It's the 5.7L Hemi BTW.

I've heard a handful of different fixes for this such as:

1) Bad EGR valve
2) Dirty throttle body (done)
3) Bad fuel pump
4) Issue with the PCM and needing to execute a TSP on it (done)
5) Dirty injectors.
6) Torque converter issue

I'm willing to spend the money to make the fix but I can't just throw a bunch of guess money at the big items such as the torque converter or the fuel pump unless I am confident that will fix the problem.

This is a somewhat common issue with these engines from what I've read.

Thanks for the replies. Keep em coming!

check the transmission fluid level, drive it till its up to operating temp, dont turn truck off and check on level ground with engine running. if its low top off with atf +4. if the level is good, it could be a crank sensor starting to go bad. but its probably the trans level, Low automatic transmission fluid causes a delayed release of the torque converter clutch and cause it to stall

Mine does it to when I fill it up all the way from being empty. A buddy of mine said it is the EVAP purge valve. He says it's actually is letting raw fuel into the intake manifold. He says i have to replace that valve. Go get it replaced, i'm just waiting on fund to do so.

Check the trans fluid level, I had this happen a few times last year and fluid level was a qt low. topped it off and it has not happened since then.

I'll try it this weekend but your suggestion seems to ignore one of the key symptoms: it only does it right after filling up the gas tank to the top.

Definitely appreciate the advice and will check the fluid this weekend when it's light outside but I must admit I'm skeptical due to, what feels like a fuel system issue.

Thanks!

well today i pulled off my cai and found ice! right at the tb and i noticed that under my oil fill cap is drops of water so the moisture from my crankcase was going into my intake i bought a little cone filter just for that hopefully it cures my problem.
