Sorry to here your having problems but it not uncommon for these model's and years of most Dodge & Chry product's to have several common problems relating to intermittent no start conditions. With not much to go on, the fact your smelling fuel brings a few things to mind. Your injector's are pulsing fuel it sound's like so it would be a lack of spark causing the no start. Most all late model's vehicles have wireless tech in them and like Window's XP's blue screen of death they will lockup. So the next time it happens, disconnect your battery post from the neg (-) cable but be careful should it have a sensor attaching it to the battery. Don't break it you have to have it. Wait 20 second's and reconnect it and attempt to start it, if it starts Dodge has a TSB # 08-007-08 Rev A that should be performed on it to help correct the problem. If by chance it doesn't start, make sure all accessory's are off and disconnect the neg - cable again and touch it to the pos + cable and hold it for 12 seconds. Sounds a little scary but not to worry nothing from the factory retains enough power to cause a problem but this will drain any excess power from the wireless and control modules long enough for a reset. Then reconnect and attempt to restart. If it still fails to start most any other testing will require a high dollar scan tool and a scope to hunt it down. Good luck.
