I have a 2000 BMW 740i and I drove it from Houston to New Orleans with no problems, I spent a night in New Orleans and the next morning when I started the car it started but was making a small rattling noise in idle, the noise intensified a little as I accelerated but when i got on the highway it went away. I got on i-10 from New Orleans and was driving to Pensacola, Fl but before i made it to Mobile, AL the car started to slow down i went from going 80MPH to the engine only allowing 60MPH with the accelerator all the way to the floor, it finally died and i couldn't accelerate anymore. I tried to start the car and it sounds like it wants to crank it just continues to try to turn over but it won't turn over.

This could be anything from a mechanical engine failure to a broken catalyst restricting the exhaust. I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
