You need a new alternator , Check your amps coming out of the back of your altenator you will find it is not sending 14 volts when its running. The reason it starts and runs for a bit after it sits or charges is that the car is running on the battery if you keep this up you will not only need a new altenator but a new battery

Your best bet is to take the vehicle to an automotive electrical specialist to have them resolve the problem there is far too many things that could be going on that could potentially lead to a fire which will inevitably be detrimental to your car but depending on the exact situation when it happens it could cause harm to you or possibly someone else

i don't know. this sounds serious. you do not want to damage your engine. a mechanic should inspect and offer suggestions. don't delay.
there may just be be a damaged or loose hose. when engine is cold make sure there is tension on the drive belt for the water pump. if possible, make sure the radiator is full and the radiator overflow reservoir is at the lower [ cold] line. if all seems OK, your engines thermostat may need to be replaced.

You most likely need a new evaporative purge valve.
Besides the engine light, another symptom is hard starting after filling with fuel, because the filling makes lots of strong fuel vapor in the tank and that gets sucked into the manifold, causing an overly rich mixture. Also, if you ignore this problem for a while, your catalytic converters will be ruined, which is a very expensive problem, that I discovered the hard way.
The valve is located at the firewall side of the engine behind the fuel injection. It has 2 hoses and a plug. If you disconnect the hose which goes to the fuel tank (the passenger side one) and start the car, and put your finger on the hose nipple, you should feel no vacuum. If you do, the valve is bad. I bought mine online for about $32, free shipping. I think from Amazon. They wanted $60-$68 at the parts stores, and they were out of stock. The vacuum hoses are kind of hard to remove. There is a tang you have to work with.

This is the part I ordered:

Make sure you put it on the right way round. I first had it backwards and the hoses are hard to get off again.

Have you tried replacing the battery in the key fob? That will usually make it work properly.

Sometimes the emission light will come on if the gasket on the gas cap is worn or dirty, thus not sealing properly. If it doesn't look worn, then try cleaning it.

You should not have to remove the AC condenser.
Drain coolant.
If I remember right you have to loosen one side of the motor mounts(dog bone things) move them out of the way.
Then remove the fan unit i think it had a couple clips and a couple bolts pull it out the top.
Remove the lines for the transmission cooler, and the two clips holding the top of the radiator in.
Then you have to search for some bolts holding the radiator to the condenser and remove them.
Pull the radiator out the top.
Put everything back together, if I remember right the hardest part was getting the condenser apart from the radiator and back together because there isn't enough room to remove them together.

It is #3 in the picture. You should be able to get at it in the engine compartment.
