Okay guys I have a problem! Over the weekend I was taking a 2 and a half hour road trip and my mustang stalled out on me 4 different times. The first time like every other time, I was cruisin about 70 at around 2.2K rpms and my car just looses all power so I push in the clutch and the engine drops to about 1K rpms, stumbles, and dies. So I pull off to the side and I will not start at all, so I wait about 5 min. and try it again and it starts then dies again. Then after waiting about 15 min. it fires up and drives normal for about 10 minutes and the whole process startes all over again. It repeated 3 different times. The temperature is running normal, and there isnt any "check engine" lights on or anything.......Im lost! Do you all have any opinions???????
Thanks
 
Sounds like a vapor lock problem which was common on the fox bodies but not so much on the fox-4 and newer. I'd be really suspicious that your fuel pump is on it's way out.(not pumping enough fuel through the lines to keep it circulating making it overheat and vaporize in the lines in the engine compartment)
 
Ive checked all of my vaccum line, and they all seem to be okay. I dont really have a solid way to check out my fuel pump because it it only acts up occassionaly....but I am leaning towards the fuel system! IS there any more ideas???????

thanks
 
Ignition problem. If it was fuel related you'd notice it while accelerating. If the fuel pump is not noisy and you kept up on fuel filters then I'd guess you have an ignition module crapping out or some other ignition related problem. Have you had the codes pulled ?
 
I whatever gas is cheapest, I usually run 89-93 octane. My car has around 90k miles on it and Im pretty sure its still runnin the stock filter. I forgot to say that when Im crusin around town it runs just fine, just every now and then it f**ks up on the highway.
