It's hard to say what is going on without a diagnostic check. For an engine to start it needs fuel and ignition, so check the fuel pressure and spark to the cylinders to see which is not working, then diagnose accordingly.

No to answer 2. Buy a car that you can afford to repair.

two things .1st fuel pump relay switch /2nd overload protection switch .there both on the inner firewall inside the hood area fprs is blk and the ops is silver with two fuses in a clear cap .theres a vent cap on the gas cap too try taking it off next time it stalls .and see if that does it ?if it does replace it .?

I had a 320SE that was doing the same thing.
And I took it to the Service center, they checked it
and found it to be a fuse linkege, I can't remember
were it was located, but they replaced it, and the problem went away. I drove it for another two years.

My 420 sel did the same thing. I had the fuel relay gauge changed and now it is fine.
