on highway and dies

[Techmonster]

hi everyone...hope you can steer me in the right direstions

I ahve a 94 X with about 180,x.. on it. I have noticed in the past few weeks that when I driving it ocassily it will just feel like it has no gas/power and just dies. It seems to only do it when I moving(not idling or anything). the other day I was doing 65 on highway and all of sudden pedal went to floor, no power and tach went to zero. coast over to side of road, wait 10 seconds and she fires up; no problems.

I am thinking fuel pump...any thoughts. It does not start hard at all, fires right up, even in cold minnesota.

It does this so radomly. It'll go two months without doing it and then in 4 days it'll do it twice. any ideas or help...thanks

Does it sputter or just shut off?

There was an identical thread a week ago. I'll see if I can find it.

Found the thread, but it doesn't sound the same: http://www.explorerforum.com/forums/showthread.php?t=147622

no does not sputter or anything...not alternator or battery, they test out just fine. read that post...hummm battery cable never thought of that, never repalced that either

When it dies, does everything (radio, lights, .etc) die as well, or is it just the motor?

 

[Techmonster]

just the motor, nothing else...dies

Pointing towards the fuel pump, fuse, or relay.

Search for those.

Next time this happens you need to lsiten for the fuel pump if possible.
Expect it to start getting worse, meaning it wont just fire right back up.

The relays and fuses have issues, especially if they have not been touched in 180K miles. Now with that many miles it could be quite a few things, but there are some simple tests you can do to rule things like the fuel pump out.

Do you ever have a check engine light while driving?

 

[MrShorty]

Especially where it's so intermittent and definitely appears electrical in nature, I'd pull codes from the computer. Sometimes a stall like that will leave codes in continuous memory (even though the check engine light doesn't come on) that will help pinpoint the circuit that is failing.

CHECK ENGINE LIGHT IS ON, HAVE NOT PULLED CODES YET...LIGHT COMES ON AND THEN GOES AWAY WHILE DRIVING. TAKES ABOUT 10 MIN OF DRIVING FOR IT TO COME ON, THEN COMES GOES OUT AND COMES ON AT RADOM

sorry for the uppercase letters...not yelling

intermittant driveability codes are usually an emissions sensor of some sort.

Pull the codes, that is the best place to start.
