Weird problem! car wont stay running. please help

[eagle talon guy]

So 2 weeks ago, my car died as I was driving (I was slowing down and about to take a right turn). Then it wouldn't start! So I got pulled home, and on the way I tried popping the clutch to start it, and it took a couple tries before it started, but it did start.. so then I got home and I shut it off and started it 2 more times.. Then I started it to go somewhere, and it ran for a few seconds and then died. and then it wouldn't start after that! then I let it sit for a while, and I tried to start it, and it started. but then it died. so I figured maybe it was the fuel pump. Got a stock one and put it in. but when I was tightening the bolt for the positive wire on the pump housing, it broke the stud.. so I rigged it by using jb weld. so that lasted a week, and then it came undone. but I picked up a walbro 255 that day. so yesterday, it died and did the same thing as I was slowing down to take a left turn.. (btw, I had drilled a hole where the stud was and put a screw in, so the connection is good) so I put the walbro in yesterday. then it started and I thought it was good.. I let it run for a bit to make sure it doesn't die, and it didn't. so then I went to go somewhere like an hour later, and it started, and then a couple seconds later, it died!
WTF could this be!?!
I am so lost as to what could cause this.. please help and let me know if you have any ideas as to what it could be..

When's the last time you changed your fuel filter? Have you checked all your grounds?

I dont remember how many miles ago it was.. but it was last year or the year before... so I guess since its only like 20 bucks, I could probably try a new one..

and yeah, grounds should be good

When it runs does it run solid or does it run like crap?

It runs alright.. It has always idled shitty.. like there has been times where it idles at frickin 3k!!! but it does the idle surge thing..

I would say try the fuel filter first. I'm assuming you have spark since it runs, but maybe one of your coil packs is going back? I'm no master tech, but I'll try to help out as much as I can! haha

[eagle talon guy]

I have another coil pack laying around, so Im gonna try that.

Have you checked for boost leaks. Sounds to me like its that. Have had issues before where the pipe will be not fully disconnected, and under vacuum its fine, but then as soon as you get any kind of positive pressure it falls on its ass. Another thing to check is the MAF.

Don't just start throwing parts at it. Did you recirculate your bov, and do a boost leak test yet?

I talked to Mike via text tonight. Apparently it's running just fine now, without any replaced parts. He said that it only does it on Friday's. Therefore, I concluded his car is possessed.
