95 Escort Stalls after 45 seconds, runs rough

[dlbdata]

95 1.9 Escort Stalls after 45 seconds, runs rough. While coasting you can feel the engine kind of stumbling & surging. When I sit at a long light it will be idling OK, then all of a sudden at 45 seconds or so it will either stall or idle really rough & slow. While its doing that if I shut the engine off & restart it, it will be OK for another 45 seconds or so. I've replaced spark plugs, air filter, IAC. Any ideas or suggestions?
Thanks.
