Runs ruff

Had this problem right after installing new Fuel Pump. problem went away for a bit, then after I washed motor it started again. First start of the day it barely stays running. If I attempt to give it any gas it dies. After 60-120 secs it runs normal, fuel filter is clean pump is 3 months old. Any idea's?

how long ago did you wash it and then find it was running rough. your TPS may have just still been wet
