My wife had a similar problem with a 2003 Jeep Liberty. Her problem was that it stalled and she could not get it restarted unless it sat off for 30-45 minutes. It seemed like it was a problem with the alternator and battery but it had just gotten a brand new battery in it and we discovered the starter would roll over after the Jeep sat. We had it towed to the dealership and they replaced the Crank Sensor and the Timing Sensor and the Jeep now runs fine again. Side note: They charged us about $200 to fix these parts.

Time to check sensors. I'd start with tps, map and mass air flow sensor if used. Many "supermarket" style parts outlets will scan your system for codes. Start there to give yourself some general direction on what to look at.(of course you will check ignition components, cap, wires, rotor and coil... believe it or not, even if there is residue around plugs, it generally won't give you that problem, though it should be blown out of there with compressed air or something before removing plugs)

Sounds like low speed coil in the Blower Fan resistor block has failed. The Blower Fan Resistor Block is usually located in the air ducting adjacent to the Blower Fan. The Resistor Block consists of 3 or 4 coils of special resistance wire attached to terminals which connect to the wiring that comes from the fan switch and then to the Blower Fan. The block is on the output side of the fan unit so that the airflow from the fan past the coils inside the duct assists in preventing them from overheating and burning out.
Access to the Resistor Block is from under the dash. To replace, remove the multi-pin connector and then undo the screws holding in the block. Check air duct for leaves and dirt which may have caused the coils to fail. .Replacement is the reverse procedure

check for vacuum leaks on every hose connected to the engine intake manifold. If all hoses tight at both ends, remove idle air control (IAC) valve as well as hose from throttle body. clean valve, idle air passages, and throttle body with carb cleaner. Hope this clears up the problem. Let me know if you have any questions.
