I dont know what to do about my Daytona(dead since last July)

Well this is an on going story since July of 16'. I'll give the highlights of what's happened. Bike doesnt start after parking at my buddies house. Have it towed to my place. After a bit of diag, find out it's the CPS. Replace it with a Ricks CPS. Woohoo, bike starts, but dies out immediately. Keeps doing this. Buy VAGCOMM cord and get Tune ECU. Reset TPS. Woohoo, it runs and idles just fine for half an hour. Come back 2 days later to make sure it starts. Problem is back. At this point I give up and take it to Triumph in October. So triumph has replaced two TPS sensors, sent the injectors out for cleaning, and as of today with a provided part from me, replaced an ECU to no avail. I talked to them about the manual idle control and they don't believe that will solve the problem either. They told me one of their tech trainers was by the other day and suggested the pulser coil, but I just replaced that and got the bike to start by doing so. Im so frustrated and just beat down at this point. Does anyone know what I could possibly try at this point?
