Hey Mr. T.,
Get a tube of this... cut a small piece off the tip..(you WILL need a caulking gun to get this out of the tube).. and maybe a friend to help pry the seal around the windshield up so you can squirt this sealer COMPLETELY .. and liberally ...around the windshield...let the seal down gently.. and let it dry.. this should seal it!! (let it DRY BEFORE wiping the excess).. https://www.oreillyauto.com/detail/transtar-autobody-technologies-body-tec-5109/chemicals---fluids-16461/glues--adhesives---sealants-19861/windshield-window-repair-17686/adhesive/4502/4749716

I would clean the throttle body first and the idle air control motor(IAC). Clean where the plate sits and on the back of it/them. You have to remove the IAC to clean it. Brake clean and a toothbrush works fine. If it still is high. Diagnostics need done for the IAC. Most times it is the IAC.

Two things I can think of. The coil is bad. They can do this from heat. They are good cold, but the heat opens a circuit and it dies. Next would be catalytic converter. It is clogged up. Check the converter first. Remove the pre O2 sensor. If it keeps going after ten minutes, This is your problem. If it dies check spark while still hot. No spark, coil. Just a note, you could still have converter problems.

 It's under the steering wheel, left of the steering column. You gotta climb under the dash to see it, and look up.

I don't think your car has one. But it has been a long time since I worked on one of these. I think you have a fuse and a master switch. Fuse good, switch is bad. If there is a relay( they rarely go bad), it will be under the dash. One of those 4 or 5 relays on the top. Owners manual will tell you. But my guess is, you don't have it. And I don't have the program for your car. Swap them around.

Replace light switch assembly. Remenber some switches pull up to flash headlights and press down to change from low to high--press down again goes from high to low.

The oil pump is inside the oil pan on the bottom of the engine on most models. I doubt it would have anything to do with a burning smell.

must be a bad wire if you put a new battery and alternator in it. Are you sure the battery and alternator are good. One way to test the alternator is to run the engine and disconnect the battery [one post] while the car is running. If the car keeps running, the alternator is good. If engine cuts out and shuts off, alternator is bad

The circuit that powers the fuel pump, ignition etc may have a bad connection in the wiring harness where the plugs come together. When extra electrical loads are being fed current through the plug connection there is voltage loss at the plug joint. Thy unplugging the multipoint connector where the wiring harnesses join together around the fusible links etc. You will be able to recognize the culprit by its discoloration due to overheating in the plug. Replacing connector pins and plug clips should take care of it.
