Help! My 94 Honda Accord Ex dies while driving, I have replaced battery, alternator, fuel filter, ignition switch, & did a tune up.

 

Need more info. Does it start right back up after it dies or does it take some time. You need to determine if the problem is spark or fuel related. I would connect a fuel pressure tester to it and drive it with it taped to windshield. Monitor the pressure. If the pressure slowly drops off and the engine dies you will know you are losing pressure and is most likely the pump or the relay. If you are losing spark you will need to go through the ignition system. Coil, igniter, distributor etc.

 

Try inspecting the battery cables/connection, I also had a similar problem ended up being my aftermarket alarm system,Just throwing it out there if you do have one.
