I had a new pump installed and unit re-gassed as the old pump leaked. New pump was working fine for a short while, now it cuts in and out all the time. I have had the gas checked and it is still fine and at good pressure. I also had a new receiver/drier put in. Any ideas?

I do not think that you have a problem, the pump is cycling to maintain cooling, you will need to get the system pressures checked as it is working this will show up any real problem, it will cycle more at idle and hardly at all at higher engine speed, is this what you are seeing?
