After driving the suburban for awhile during the day and it behaving fine, when it was driven for a pizza run that night it only got about a 1 1/2 miles up the road before it died. Cleaned battery cables after about 1/2 hour (tools needed to be delivered) and started right up. Same thing happened. This time got another battery, started back home, went about 3 miles this time before it up and died. Starter was replaced about 6 months ago. Help.

Next time it dies out

If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start

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
