My BEC is fine, my steering worked yesterday.

It could be a loose connection, but i would understand i had crashed and it started behaving like that... but i was just driving in a straight line when it started to cut out ???

Edit: I had time to check my set-up and when I turn the BEC off, the ESC doesn't go through it's start-up beeps again - so it doesn't sound like a BEC problem would cause exactly what you are seeing.

Now you could lose power if the BEC dropped off, because it powers the rx, but that wouldn't explain why you get the start-up beeps again.

I think the ESC must be losing power from the lipos to exhibit that behavior, or the ESC itself is faulty.
