Fuel I've replaced the main relay switch and fuel pump and fuel filter but still have the same problem. I can drive down the road for 5 min then the car dies, wait about 10 min and the car will start and go for anouther 5-10 min and dies again. What could it be???

It's an electrical problem, not mechanical (read: fuel filter is a good idea, but will not solve this symptom).   
My diagnostic efforts would be directed to the ignition system first,as the symptoms sound like igntion more than fuel, and it's more complicated has more components, hence has more potential to fail.  Get a haynes manual if you don't already have one and use the diagnosics there for  ignition circuit and fuel system. available at autoparts store, amazon or haynes.com.  It will be the best $20 you spent for your car.

Do all the other electrics work well when the car dies, check if headlights are dim and if the starter turns over strong when it dies?   If not it could be a bad ground on either end of the 2 battery cables.  If all other electric works OK when it dies, and you still think it's a fuel delivery problem,  concentrate on the fuel pump circuit, pull the fuse and look for any slight corrosion, if found you need to at least spray electrical contact cleaner into the socket (use saftey glasses!!!) and clean the fuse or replace it.  trace wires to fuel pump and find terminal connectors, pull them off and do the same thing.
good luck, I miss the '89 civic 1500 i used to own .. a tight, solid, fun little car

Go spend 250.00 and buy a distributor.. it will fix it and you will be on about your day in 15 minutes.... its the coil INSIDE the distributor that is heating up and losing spark

Lets start at the beginning. The engine computer grounds the pump relay. The relay gets power from the EFI relay when the key switch is on and from the starter fuse when the key switch is in the start position. Do you know if the pump relay is getting power from both sources and a ground from the computer ? Can you run a hot wire to the blue black wire going to the pump and keep it running ?

On some models, the Engine Control unit has a power supply relay. These relays some times get internal dry solder points. After driving for some time the the solder will get hot and separate. When it cools down it makes contact again. You will have to replace this relay or open it up and re- solder the solder joints. The relay is usually located on the main relay station in position 3. the relay station is located behind the right dash panel.[right hand drive vehicles]. You may need to refer to a manual for your specific model to find the exact location of the relay.

It's either the fuel pump or your engine control unit. Try hot wiring the pump and see if it works. If it does you need a new brain.

My truck 99 ford ranger died while driving down the road


fuel filter usually dont cause it to die and not start back, thay usually cause rough running. see if your fuel pump is running by getting in and roll up all windows so as quite as possible then cycle the key from off to run and lisen for the pump to run for 2 to 3 seconds should be a faint buzz sound if no sound is heard then replace the fuel pump relay, if no help probably going to need fuel pump
