Help diagnosing 06 Daytona.

I picked up a 06 Daytona that was used for track days. Its been lowsided at least once but repaired and ran fine since. Bike sat up indoors with race fuel in it for at least 5 years.
I cleaned the fuel system and the rest injectors at least 4 times now. Etched and coated the tank on the first attempt. Their wasnt heavy rust inside the tank but it was present. There was a light brownish red residue on the top of every surface. I also dissembled the fule pump as far as was reasonable and cleaned it. Backwards flushed the fuel line, fuel rail, and injectors multiple times.
Each time bike will start an idle for a few minutes then die. If i try to rev it up it will intermittently rev then cut out then rev. Fuel system is clean, fuel is fresh. Trying to figure out what to check next. Any ideas?

Check that your MAP sensors and TPS are plugged in. If the engine is getting more air than it expects, it'll lean out and die.

Ok will do. I ordered a set of coils which will be here this weekend. Plugs have already been replaced.

If this doesn't work I'm leaning towards maybe a stator/CPS swap? Ive read a few posts about the CPS causing these problems but it seems they only come attached to the stator.

Also the R/R was previously swapped to a mosfet by the prior owner when the bike was running correctly.

Ok new set of used coils from a 2012 installed and literally no change in the bikes willingness to run.
It will barely try to start then give up 2 seconds or so after. Also checked the stator / CPS and confirmed that they had been replaced by new units from Ricks by the previous owner.
Being it that the bike has run the best / longest immediately after having cleaned the fuel system. Im leaning back toward a fuel delivery issue.
Next items on deck:

Double check for vacuum leaks
New fuel injectors
Check fuel pressure
