Misfire after warm restart

[Clutch450]

Weird misfire problem
I've owned this car for 4 months now with no problems. But today I went to the store. The car ran great there. Then after 10 minutes in the store I come out to start it. It starts but starting it seems like the motor kicks back. Like starter is struggling.
Once it's started it idles rough. And misfires. When trying to drive its like driving on 3 cylinders and backfires bad

I shut it off and start it a few more times. Runs perfect again.
Same situation occurred when I got home and go to start it a few minutes later

No CEL's. Changed plug wires and power transistor and checked plugs. But the problem still occurs

Car is a 2.4 block run by dsmlink v3
It's been raining a lot here recently, not sure if driving it in the rain for the first time today has an effect on it or not.

Any helped would be great!

Now the problem occurs all the time. Even when cold. I can't drive the car at all. No power
And it's not vapor lock. I unhooked the vac line from the fpr but still no fix

I pulled the injectors today. They had a black sticky residue on them. I cleaned them really good. Car started up just fine.
I come back a few hours later and the problem is there again. The motor is kicking back so hard that the starter is completely toast now. And no I was not sitting there cranking for 30 seconds at a time. These were like 5 seconds turn overs. The motor just kicks back hard and back fires.

I cant really just swap injectors since they're 2150cc on e85. Car would start and run pretty bad on smaller injectors.

This is a serious problem. Ive been working on these cars for years and have not yet come across a problem that has confused me so much.

Coilpack is good
Plugs are good
Plug wires are good
Power transistor is good
I do have spark
Fuel pressure is were it should be
Fuel pump is working good.
I can't really believe it would be an ecu related problem as I just bought this eprom and link setup from ECMtuning only 30 days ago.

Link is setup to not search for random misfires, so it cant be that.

I was planning on taking this car to a huge car show in OCMD next week. It was running perfect up until a day ago. Figures!

I posted here and in the newbie section, just so I could get as many opinions and help as I could. I seriously need some help here guys. Im lost as of now
