When I first start my truck it takes for ever to go through the gears. Its extremely sluggish for about ten minutes even when I let it sit for about five minutes andvwarm up. Is it my f.p.r.? It seems like it isn't getting enough fuel.

Any suggestions?

Have you measured fuel pressure?

I took the vacume line off from the vacume tree and blew into it and it gave a little bit what else should I do

Have fuel pressure measured, and read the codes. There's a small (something looks like a tire air valve) at the fuel ramp. You'll need a measuring tool for this operation.
Here's how to read the codes - https://www.f150forum.com/f10/how-retrieve-trouble-codes-obdi-10907/
