Engine revs up and then it idles down and dies. I already did a tune up. When it idles down if I push the gas pedal down it doesnt die. It has even died when we were driving down the highway.

Engine revs up and then it idles down and dies. Duplicate the problem when it does-immediately do below

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not 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 problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
