Sounds like fuel starvation to me, especially if the scenario repeats itself! Take out the fuel pump fuse, and put an ammeter (which measures current) in series with the fuel pump circuit, and start the engine ... then watch the current reading. Does it start falling off? If so, the fuel pump is losing pressure, starving the engine for fuel!

Under drivers side dash or in the driver kick panel area

Check ground wires. It is old and tired.

the fuel pump is located in the fuel tank and it must be dropped to replace.

If the compressor locked up the chances there are metallic parts in the rest of the system are great. Flushing out the system is best left to professionals. If your system has not been converted from R 12 freon to R-134a freon, now's the time to do it. The oil in the R-12 system is not compatible with r-134a. If there is still freon in the system you cannot simply discharge it into the air.. The fine is huge. Have an AC shop do the work.

With the key on press the off and warmer buttons together and hold for 10 seconds or so the display will show you trouble code like E.1.0 these codes will help you determine what is wrong. But sounds like the anti-theft is active.

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Check the timing and coil packs and check the firing order to make sure they are correct otherwise it could be a bad PCM

oh yeah ,,,you need to check all of those vacuum lines ..replace all dry rotted vacuum hoses and connectors ..you will find all of them running from your vehicles intake

I would suspect sticking linkages. Spray all the linkage, especially on the choke side with penetrating oil and work it all back and forth.Make sure you engage and disengage the choke linkages manually through all its functions. Then spray it all down with a good lubricant like white lithium. If you have the vacuum and heat operated choke then quite often that will gum up. Take it apart enough to get the piston out and soak it all down good with penetrating fluid.Wash the piston off and slide it back together. When it slides in and out easily, then give it a quick spray with lube and put it back together.

Did you check the fuses in both places?

replace the power switch
