A/c won't stay cold.

Hello all. I recently purchased a 99 Ranger standard cab 2wd 2.5 liter. I have never owned Ford previous to this truck. Love the truck. I maintenance myself. Just recently replaced a cracked head and rebuilt from ground up. Runs great.
Ok. Problem is have is the a/c. I have completely de-vacuated and recharged. Blows ice cold for about 5 to 10 mins. Depending.
I switched relay out and same result. I did notice the relay getting really hot. And than the clutch disengaged. All wires are grounded and clutch dose not seem bad. Any thoughts...
Thanks in advance
