I was driving it on the freeway @65mph up a incline, the motor stalled. I managed to coast down a offramp and tried to start it unsucessfully. After about 20 mins I cranked the starter for about 10 sec. While stepping on the throttle and it finally fired up. I drove it about another mile and it died. I had it towed home, and about 3 hours later I tried starting it and it fired up no prob, w/o stepping on the throttle. Since then ive started it and revved it up and such several times, but kind of leery of driving it.I replaced the fuel pump, and filt. Back in feb. @ 122k miles

Next time it happens don't wait for nothing do below immediately to determine if its fuel or spark

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, 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, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing
