If it has spark when it stalls, it has to be a fuel-related problem. The filter will never solve that on a Chrysler product except for the diesel trucks. The best place to start is by teeing into the fuel supply hose near the right strut tower and connecting a fuel pressure gauge to see what's happening. How do you know the fuel pump is good? They rarely quit while they're running but there could be a pickup screen that is getting plugged. The symptom would be stalling when the largest fuel volume is being pumped, ... Which is during coasting. The engine will run fine during acceleration and cruising at highway speed but will stall when you take your foot off the gas pedal.
If you suspect a plugged pickup might be the cause, try disconnecting the vacuum hose from the pressure regulator and plugging it. That will make it run too rich and you might see black smoke from the tail pipe, but it should not stall.
