Unhappy need help! it acts like its missing. 90 eclipse

I have a 90 2.0 turbo eclipse fwd. Out of the blue it started not running right. I came to a stop and when I started going again it felt like it was missing. it sputters when starting out and when it is bogged down like doing 30 in 4th and when it is past half throttle. If I start in 1st and punch it it revs and builds boost then falls flat on its face and I loose almost all power. But the strange part is when I first start it in the morning it runs great for the first maybe 5min. I checked plugs and wires and changed fuel filter. someone mentioned it might be o2 sensor. I replaced the ecu about 2yrs ago and haven't had any problems tell now and its kinda acting like it did when I replaced it last time except it wouldn't want to start after driving it last time and it does not do that now. any ideas would be useful. Thanks

How old are the plugs and wires? Also try doing a boost leak test.
