Ok I recently bought a 93 eclipse 1.8 non-turbo. And I was driving home one night and turned the highbeams on and it started to die a few miles down the road it did die.I took the alt. Off and had it tested but no such luck it was a bad alt. So I ordered a new one but it still dies what can I look itno I had the new alt. Tested twice and it was a good alt. So whats my next step?

Duplicate the problem and immediately do below don't wait for nothing something has to give

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor camshaft and crankshaft sensors- Note: If it doesn't apply disregard it
