is your throttle body idle hole clogged? if you have fuel and spark the only other thing you need is air to start. unless your engine is not turning over. when you run the starter does it actually turn over the engine?

On the other hand, if you don't want to take our advise, just follow freegdr's advise and have it towed to a shop.

put a compression test to it......but unless you jumped time on the timing chain (uncommon on 4.0) you should run..are you sure you have injector pulse just because you have pressure doesn't mean the injectors are firing

WOW that is important.....if your plugs are fuel soaked then you have no spark or very weak one...and my grandparents had an intermitten shut off problem it ended up being a broken wire in the main harness on the firewall it took weeks to find
