Question about Jeep Wrangler
Are you also losing fuel economy? Is the vehicle still warmed up/hot when you are trying to start it again? How many miles have you driven since the last time the throttle body was cleaned? Does it also have a rough idle until it's warmed up?
My guess for now is that the electronic choke/IAC valve is gummed up and sticking. When a vehicle is cold, the valve is supposed to stay open until it is warmed up and the idle speed goes to normal as it reaches operating temperature at which time the valve will close. When the throttle body gets hot, the carbon build up and mixture of any oil that will get on the valve gets sticky so when it needs to open it is slow to do so. If you don't know what the electronic choke or IAC valve is for your Jeep, look it up on a parts website, find it on your vehicle, remove it and clean it with a throttle body cleaner and replace...make sure you don't lose any gaskets attached to it.

The fuel-pump relay unit is responsible for turning the fuel pump on when it detects the engine is running. When the ignition signal stops, the fuel-pump relay switches the pump off. Problems with the ignition and starting the vehicle often can be traced to the condition of the fuel-pump relay.
