I would first check the motor and transmission mounts. Then the universal joints.

Acts like dead battery, jump starts, and can drive, but turn on the a/c and whole thing dies and I have to coast to parking and jump start again. any ideas?

you need to check the charging system voltage if the alternator is not putting out voltage the car is only running off the battery and the battery is not being recharged turning on the ac adds the drain from the cooing fan about 30amps and the blower motor inside the car another 20 amps and also the compressor clutch of 20 amps

Power loss

I have had flickering dash lights and most of the time the whole car shuts down, we coast, and then it restarts itself!

I just traced wiring and found the main power cable from the battery almost burned through where it goes past a heat shielded tube on the engine. The braided fabric heat shield is burned through and the tube has bits of copper wire welded to it. I just taped it up and will test drive later. Check the main power wire where it leaves the battery and heads back past the engine.
