This sounds typical of a plugged pickup screen in the gas tank. It will cause the engine to run fine when cruising or accelerating but it will lead to stalling when the highest volume of fuel is being pumped, which is during coasting. You can identify that by driving with a fuel pressure gauge stuck under the wiper arm, then see what happens to the pressure when the problem occurs, or you might try unplugging the vacuum hose from the fuel pressure regulator and plugging it. That will cause some black smoke from the tail pipe and excessive fuel consumption, so just do that long enough to verify the engine continues to run better.
