Hi there, everyone!
New-comer in piloting the DC-8 (-63) And just a few minutes ago, when I was cruising at FL350, I found that my airspeed dropped to below 200 kts. And when checking the instruments, the problem was discovered:
All 4 engines of the DC-8 has Flamed out and providing no power.
Is there anyway to solve this because I have experienced that before and it lead to a stall that no one knows, the flameout happened SUDDENLY without any warning.

Under normal circumstances I'd suggest virtual "FUEL" .... or rather the lack of it .... to be the cause of your problem .... because I've never heard of any such issue with the HJG DC8's or any other HJG simulation for that matter either.
These simulations have been available since around 2000 .... transitioning through FS2002, to FS2004, and reasonable compatibility within FSX (and improving along the way) .... although they aren't FSX native as such.
Over the past 14 years these simulations have, by now, become very well understood .... and to be perfectly frank (but not wanting to appear the least bit unhelpful either) .... no such issue, that I can can recall, has ever been reported in regard to any of these simulations.
I presume you're using HJG supplied panels .... and FDE .... and have made no adjustments, whatsoever, to either ?
Again .... check you fuel status .... for starters.

1 following thought just crossed my mind ....
By any remote chance .... have you .... even inadvertently .... activated one of the FAILURE modes (AIRCRAFT/FAILURES .... top menu bar) which is built into FS ?
Doing so (in regard to sumulated engine failures etc) could, conceivably, be responsible for generating what you're experiencing.
In the absence of any known problem .... that's all I can think of.

Well,
On that flight, I am sure I got enough fuel and I NEVER messed with the default failure modes.
But, will any add-ons will affect the aircraft itself? (I used FSPassengers on that flight)

Check those FS "FAILURE" modes anyway .... just in case.
In the case of add-on products and utilities ....
I'm not familiar with the product to which you refer .... so .... can't say whether or not it might have potential to generate a problem like that which, you say, you've experienced .... BUT .... many years of experience, here at HJG, has taught us that some add-on programs and utilities (payware and freeware) can be responsible for generating issues that under other circumstances simply don't occur.
As I mentioned yesterday .... and as DC8 SUPPORT feedback on these gforum pages will confirm .... no such problem (as you appear to have experienced) has ever been reported to date .... short of actual "fuel starvation"/insufficient virtual fuel being loaded in order to be able to complete ones flight.
I suggest you peform the same flight again .... BUT THIS TIME .... without using the FS PASSENGER untility (or even going so far as to isolate/uninstall it) for this next particular flight .... and then report your findings.

In addition to what Mark says, I would suggest checking that you have not inadvertently switched between saved flights. I know this can happen on FS9 so I imagine it still exists on FSX although I have never tried the FSX platform myself. Basically, it comes down to how the game reads generated flights and it is possible to switch between a parked up flight and a cruising flight within the same session. Normally, the game will pick up the discrepancy and recover the flight to its actual settings but I have experienced individual engine failures due to a similar effect. Re-reading your post suggests you had been in the flight for some time so the other issue I can think of is that you have/had a stuck key on your keyboard. It is how I got an inadvertent gear extension on climb out from Corfu in a B737-400 that I mentioned on another thread although in my case I more likely caught the key by accident. As you and Mark suggest FS Passenger would be a prime suspect given all other factors being eliminated.

OK, thanks to you all, I'll have a test on that.

It turns out that it may not be the aircraft's problem but the Addon's problem, thanks for everyone's help

I'm confident it's not the simulation .... because I don't know of/can't recall any circumstance (other than those which I suggested above) which results in engine failure such as you've described.
Some (though not all) add-on programs/utilities can have a detrimental affect on other simulations.
HJG can't guaruntee it's simulations are going to be 100% compatible with every other add-on utilities/programs .... of course.

I am pleased you found the problem ray7675. I am not so familiar with add-ons and how they interact with FS aircraft so I have learned something too.
