Could be a bad coil, or ignition module right by the coil. Both will cause this. If you loose fuel pressure, it would be the pump. But pumps will usually start chugging before the engine dies. Most times it is the coil.
You may potentially have an serious electrical drain in your car circuits. The drain is slow and continuous, draining your battery charge even if you do a start. Check the cabling and look for load on your battery with a Volt meter to check for any charge drainage. Check this as a precaution before replacing any more parts.
