AC compressor clutch engagement question

I am trying to diagnose why my AC clutch won't stay engaged. It's on when I start but cuts out soon there after. I haven't checked pressures yet because I don't have the tools but when it's on it cools to about 48 deg F. It's not a clutch problem because when the clutch disenegages there is no power to it. I jumpered the clutch and it runs.
I've checked the freeze switch and it has 2.5 volts exiting it. Pulling out that lead does shut off the small fan.
I was thinking that the pressure / refrigerant level is low thus switching off the compressor but what i'm surprised by is that the fan (small one in front of the condensor)continues to run after the compressor clutch kicks off.
Any thoughts as to what the problem could be?
