WHAT CAN I DO?

2000 Volvo S80 • 60,000 miles

The engine keeps going off while I am in motion, when I am in traffic, just stepping on the gas/slowing down during traffic. But it comes back on immediately if I shift to the neutral gear and crank engine immediately.

Will it do this when you are accelerating also or only when your foot is off the throttle?

Start with basics. Fuel pressure, spark checked. Is the check engine light on?

The check engine light usually comes on when I just turn on the engine and disappears after about a minute or two(will try the five step method I saw on some reviews later in the day). Initially, it used to go off like once in a long while, lately it became more regular. It goes off when I am in motion and my foot is on the throttle.

It could be something like a crank sensor intermittently dropping out but it will be very hard to test and confirm.
