HELP! Options

OK. So yesterday on my way to work my car keeps stalling (it was warm because I let it idle for about 5 minutes.) It just idles really low and keeps falling, then raising back up and stalling occasionally. So I take it home for lunch just to see how it runs and its warm but it runs ok without stalling and idle is pretty consitant. On the way back to work it keeps stalling again (its warmer this time as I let it warm up again.) Then last nite I take it out again to see how its running. It runs fine! even after warming up. I drive around for 15-30 minutes no problem. I drive to work this morning and its fine again. On my way home right now its running like shit! It keeps surging and it sounds like its missing, but it runs fine for a minute then erratically misses and surges. And every time It surges up I hear the computer making clicking noises. I'm assuming that its the computer anyways as its coming from behind the motor. Neil Just replaced the ECU a week or 2 before I bought it. Do you think that this ECU is bad too? Is there something that is causing my car to eat up ECU's? I think it would be a good ECU as Kris sold it to him and I've known Kris to be an honest person. Any help would be greatly appreciated. Oh yeah- I also noticed that my stock boost gauge surges along with the RPM's. WTF is that? Thanks guys!
