Sputters and jerks lights dim but stay on then engine quits. If I leave it alone for while it will start but after a minute or so will eventually quit. Fuel pump or electrical problem?

Check the battery and alternator if okay and next time do below immediately don't wait for nothing to catch the cause:

Get a helper 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, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
