I thought I put that in my original post, CEL isn't illuminated, I jumped the terminals when the problem began, and I didn't have any. Ill check tomorrow afternoon and see if I have any, but the last time I checked I didn't.
7mgte starts, runs rough, then stalls

Any ideas what it would be? The Igniter test pointed to it, but if you have a better idea I would be happy to hear it. I don't want to false diagnose it and spend money where it isn't due.

Wouldn't the car have to run for a set time above 200 rpm for the CEL diagnosis to do any good?
So I tried to pulled codes. I believe its code 11? Maybe Im wrong. There is a video below of my CEL.

Depends on the code but in most cases no.
OP: Reset the ECU and see if the 11 comes back. You may have other codes but they won't be displayed as long as that one is active. If it comes back it'll need to be fixed.

Ill reset the ECU tonight, Ill report back tomorrow
On another note, I cleaned up the battery ground to chassis, it was a little rusty. Tightened the grounds on the manifold, I cant find the ground strap from the head to the body anywhere.
I read a post by jetjock that made perfect sense about the grounds not being the problem and it being B+ After I check codes tomorrow, Ill send B+ voltage to ECU and see what happens.
I left the battery cables off all night. This afternoon I reconnected them and started it up and it ran find, slight miss, but idles pretty good, revs good. ran it for about 2-3 minutes no issues. shut it off, and went to check codes. The CEL just flashes when I turn the ignition on with the terminals jumped. Im searching what that means right now. No luck yet.
When I took the jumper wire out, I glanced over at the exhaust side of the engine and I noticed a large gash in the BOV hoses. I pulled the valve off, and the hoses were trashed. Im gonna see if I can find some hoses today.
How does this code 11 work? I mean if just resetting the ECU made the problem go away does that mean that the code popped up awhile ago, and just kept causing the problem? I guess Im asking, if I still might have a problem or if the code 11 was set on a drive and just caused issues.

It means there aren't any codes set.
The 11 means at one point there was a loss of power, even for a moment, to the ECU.
Having a code set doesn't mean there's currently a problem effecting engine operation. The MIL being on means that. The code is a soft fault while the light being on is a hard one. In other words if the MIL isn't on the ECU isn't doing anything to the engine other than what it's supposed to be doing when operating normally.
As for the hoses, a thorough visual inspection should be done when issues first arise...
Would the 11 code have caused my issues? Even it being a soft code, or is there still likely a problem?
I should have been more thorough when I inspected the hoses, Im going over all of the hoses this evening. Thank you for all the help you've been, I really appreciate it.

No code 11 would not cause yor prob as jj already stated. Now on to your lines. Make sure they are all good!!! When you did the headgasket all coolant lines, vac lines and any other hosing that you can. Not trying to be rude but just letting you know from my own personal experience.

When I did the head gasket I replaced upper and lower radiator hose and some other lines. Don't worry your comment wasn't taken as rude, I know I should have checked the lines, I just didn't do as good as inspection as I thought. When I get this line line repaired Ill drive it and see what happens. Thanks for all your guys help.
Dylan, codes aren't the cause of symptoms and clearing them won't repair the underlying fault that set one in the first place.
Now if you're asking whether a loss of power to the ECU will make the engine run funky the answer is yes but the loss has to be longer than what it takes to set the code. Longer still and the engine won't run at all.
You're just gonna have to wait and see if the problem reappears.

Thank you, thats what I needed to know. I guess Im just gonna have to be patient and see what happens. I just wasn't sure if with that code present it caused the ECU to go into a safe mode, so as not to damage the ECU or anything. If that makes sense.
There isn't any "safe mode" for momentary ECU power loss nor will the MIL illuminate when it happens. Another reason to periodically check for codes. Every oil change is a good time. That said it's not uncommon for these cars to run fine yet still set an occasional 11 due to their age. In my experience that particular issue usually involves the Main EFI relay.
