was driving home from irvine last night on the freeway, suddenly my car dies, slowly...I push it off the side of the highway and try to start it back up, nothing. I try again 10 minutes later and it fires right back up!
So i hop back on the freeway, drive a 1/2 mile, and the same thing happens, it dies.
I unhooked the alternator today and took it in to get tested. Its fine.
Mind you i can still start my car and drive it down the block, it'll just die atfer awhile.
Any chance its the fuel filter? I don't have a chilton. Could someone please point me in the right direction so i can check it? What do i have to remove to get to it?
rear diff is the pumpkin looking thing between your two rear axles. look in front of your gas tank. you'll see a silver cylindrical thing with a tube on either end, that's your fuel filter.

I would suspect the TFI module first. It is attached to the distrbutor, and held on with two screws that you will need a special tool to remove. When they go bad they cause the engine to shut off when it is warm, which is what your car is doing.
The fuel filter is located on the pass side in front of the rear axle, and you will need to get the line disconnect tools to remove it, they are available from Ford for relatively cheap. They snap into the lines and release the springs which hold the fuel lines onto the filter.
Doing both of these things should cure the problem.
After it dies check it for spark. Take a buddy with you so they can crank it while you put a screw driver in a spark plug and put it about 4 inches away from metal and see if it conducts, move closer to the metal as cranks. I use cylinder 8 wire and put it on the a/c compressor.
You can check the fuel filter by blowing into both ends , one end for suer wont let air through, but one should if it is clean, gas will come out initially though.
To take off the module you will need a special tool or a filed down socket. Try wiggling your ignition module harness too.
I would bet money that it's the module. If you replaced the module, make sure you put the conductive paste (white stuff) if it comes with it. If you dont, it will overheat and die prematurely.
I would go ahead and change the fuel filter anyways, it's only about $9 and it makes a huge difference on accelleration if the old one is dirty.
Disconnect the Ignition Module (TFI MODULE) and take it to your local AUTOZONE, they test it for free.
If the ignition module is good, then your problem is the "PICK UP COIL"
it is located inside the distributor and you have to dismount it to get to
the coil, then take the whole distributor apart to pull it out. I would personally recommend you to change the whole distributor with a new,
or rebuilt one. I had the same problem, replaced the TFI module, the problem did not go away, opted to replace the distributor with a MSD unit, because it's PICK UP COIL is maintenance free , but a rebuilt one would do.
Good Luck
Replaced the Fuel Filter, and tested the TFI module which was also good.
I just fired the car up and took it for a drive, no problems. However, i only drove a short distance. I did let the car warm up completely, i just drove close to home. If i have the problem again tomorrow when i go out for a drive, i can probably assume its the pick-up coil?
I don't think its the fuel pump because i can hear it alive and working well.
