How many miles? V6? Have you had a tune up(spark plugs changed..AT LEAST)? Should be changed about every 60,000 miles, according to the manual. Does your engine burn oil? Check your intake rubber tube, vac lines, pcv tube for crack. Hopefully your catalytic converter isn't the problem due to above...

the cooling system is a few different parts, you have the radiator, the water pump, and the fan. Are you leaking any fluid, you can do a pressure test to sell if it is leaking, are the fans kicking on when the car warms up.. If the pressure test doesn't show no leaks and pressure doesn't drop then start with looking at water pump and thermostat. Be careful because if it get to hot you can blow a head gasket.

check your cadillac converter might be going will lose power

This engine is fully electronically controlled, so you need the dealer to do a full diagnostic of the engine control system, it is the only way to get to the bottom of this. Make sure you can show the dealer exactly what is going on otherwise if they can't duplicate the concern and no fault codes are present they can't fix it.

tranmission is sliping or low on fluid.is there a lot of miles on truck.engine not lossing power transmission is sliping.

might be an AC compresser thats bust

Sounds more like an ignition control or coolant flow problem. Or, a/c fan not coming on with a/c.
Getting the water pump question out of the way, the pump either works or not. If it leaks it will cause an overheat due to coolant loss on flat ground or grades...doesn't matter. If the pump bearing or seal is bad it will still pump, it will just be loose and noisy. Coolant flow through the radiator is also essential...I don't think you have a problem there because generally this happens with less maintained higher mile cars.
A bad map sensor can cause your problem because it changes both ignition timing and fuel mixture, either of which can cause very high temps in combustion chambers especially when under a load. Mass air flow sensor can also do this but usually will cause idle problems. If fan is not on with a/c if the remainder of your cooling system may be enough to maintain decent temp control but cannot do this under a load. A/C turned off removes some load and therefore allow you to get up hills. Operating marginally, you can be pushing some coolant out of the system at times without even knowing it.
Now, about your engine: These engines are in my opinion a very poor design to begin with. Even with the best maintenance and low miles, they don't handle temperatures well. at this point, I'd be concerned that after repeated overheats and near overheats, your head gaskets may have started to fail, even though they were not the cause of the problem.Keep that in mind.
Have the items I mentioned tested. If you finally have the problem solved I suggest you change the thermostat as well...Overheating makes them unreliable.

It may be a leaky injector. The injector is connected to the bank. 1 of 2 fuel rails.

To start out with. You left out some very important information. Like: the miles on the engine, the miles on the spark plugs, electronic ignition or points, but, I will attempt to give you some pointers and areas to check.
First off, I don't believe the rusty gas tank with the hole in it has anything to do with your problem. Dieseling... I guess you have to understand the differences between a gas engine and a diesel. Basically is: a gas engine runs on spark and a diesel runs on glow plugs and compression, lots of compression. True dieseling usually is a result of having a carbon build up inside your cylinders, usually on the valves. The carbon glows when it gets hot and when the engine turns over opening the intake valves it lets in fuel.Even when you shut the engine off it still makes a few turns, causing the intake valves to open letting in fuel and if there is carbon present and it's hot you may get dieseling. You also may experience what appears to be dieseling from having your timing off. It could be from having a timing chain "jump" a link, (alot of miles on the engine) or it could be from the distributer being out of time. Both may cause loss of power and the "appearance" of dieseling. It sounds like to me that you may have a lot of miles on this vehicle and it may be loosing compression thus causing the loss of power climbing hills. Loss of compression could be caused from worn rings, bad head gasket. The block section of the engine. Or: cracked, worn, or brokrn valves, the heads of the engine. Which may explain the dieseling. Bad plugs and bad plug wires can also result in the loss of power you are experiencing while climbing hills, but you would more than likely experience the engine missing, which you did not say you were experiencing.
You may want to check with a local salvage yard for another engine if the rest of the vehicle is "worth" saving or plan on doing a compression test and more than likely...some "heavy" wrenching and rebuils you engine.
I hope this helps you. If it does please let me know and put in a post about it.
Thanks!
