You have a temperature problem. The circuit heats up and shuts down due to high resistance. After it cools down it works fine.
Would like to know the answer to the above questions. Carb is not a problem (I don't think so).

As asked before, what lights come on on the IP?

When you turn the key on, do the warning lights come on the dash ?
Can you turn the headlights on ?
These answers will help narrow down the problem to the main circuits or just the key switch.

SOURCE: Lost electrical while driving. Nothing works.

OK this is the part where You take out your test light or multimeter (best) and start chasing down the disconnect. begin at the battery and then go right to the starter to begin with, then the accessory side of the ignition switch. Once you covered these items continue from battery again and go item by item till you find the problem. Don't forget you need a good ground, regardless so make sure that is good as well. Only do testing after verifying that your battery is fully charged and can withstand a load test, otherwise all testing is invalid. After finding the problem, check the charging system to make sure it's working.

SOURCE: starts up in am after drivimg an hour shut off

It sounds like the carburator needs to be rebuilt. If you have to hold it to the floor to get it to start that means it's flooded. So, the carburator is leaking gas into the engine when it's not running. Are getting poor gas mileage too?

I would start by checking main fuses under the hood. water could have cause a short also check battery cables to see if they are heavy enough to carry the amp load needed to start the car. factory cables are not heavy enough after a few years.

06 Colbalt Electrical System Dead

I would go to the positive terminal on the battery anjd check for black hard build up on the post and inside the terminal. This is lead sulphate and cause a high resistance to any high current flow. Clean both with sand paper until shiny and refit and tension properly. Do the negative also as it will have build up but to a lesser degree. If the battery lead runs through a connection box Check for tight connections there also. As to towing most towers have a wheel rack that fits under the tyres and lifts them clear of the road so it can be taken to to a shop.

Make sure you park with the wheels straight. Sometimes the steering lock is real tough to disenguage if the wheel is shut off with it not straight. This vehicle is particularly tough at times. Next time you're in this jam, you should be able to yank on the wheel in one direction or the other and it will free up the ignition to turn on.

2006 CTS: Wouldn't start (not dead battery) Burning rubber smell.

My first guess would be the fuel pump is going bad. Sometimes jarring it a bit will make it work again and the tow may have done it. If it does this again have someone bang on the bottom of the gas tank while cranking, if that cures it then you'll know for sure.

Can't get car out of park!!

This may seem like a silly solution but it's worth a try if it gets you out of this jam. I believe the Kia has a safety feature where it won't let you shift the car out of park unless the break peddle is fully depressed. Try stomping on the break peddle while you start the car. Then see if it will let you shift out of park. If this doesn't work try pumping the break peddle a few times and try it again. If this doesn't work check the fuse box. Maybe the fuse for the actuator in the gear shift lever that lets you take it out of park is burnt out. I hope this helps you out.
