When I went from stock os to the Cos3 2bar tune.
When I reflash my truck it will run for sec than die. I had to do this two or three times before it run on it's own. Do need to do a crank re-lean after you do this or this common thing.

Not saying I'll know how to help....but it always helps to post your tune so others can see if there's any obvious issues.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

Might just be your idle learning. Which might suggest that your base map might need some work
If its ok now Id say thats what the problem was. Look into the RAF and Idle transition tuning notes.

Did you follow the COS tutorial...?
Did you do full flash of COS followed by cal flash of your old tune...?
Is your COS file compatible with your old tune as listed on the COS tutorial page 4...?
