Hello , so it took me a while to remember what i did to fix alot of issues lol been busy installing the 3in body lift from performance accessories.. ugh the body blocks ... anyways..
First the electrical. So to shorten the story i was talking to another individual with his help narrowed it to heavy corrosion down stream on both positive and negative wires off the battery along with a blown out fuseable link.
The TPS wires that go back to the harness near the alternator i believe was also showing signs of a bad wire and went ahead and replaced that 1 wire of 3 as well .
The car dying after warm was related to a holes in the brake booster gasket and a few other vacuum lines i didnt see near the transmission.
I also replaced the fuel sending unit and found water in the tank and replaced the fuel filter as well and primed everything making sure there was no air in the lines ..
So far this old gal runs now with no real issues . Hope this helps??
