Ok so, I just got the car road tuned on MS2 system, it ran good. I left it for about 5 hours and came back and it hesitated to start, It ran but really rough and when i applied gas it died, Now it gets fuel,spark, it turns on sometimes but for only a few seconds. I've checked for and vacuum leaks, doesn't seem toi have any. Would anyone know?

thanks for any help
