Pump loosing prime, output fluctuates

I just installed a new pump as my old one cracked over the weekend. I noticed that the pump doesn't keep prime. When I do get prime back, the PSI fluctuates a lot (from around 10 to 35) There is also a gauge on my well that shows negative pressure and that goes down to 0 after a couple hours. I have a backflow preventer on the line that was replaced last year, could it have gone bad already? Any other ideas as to why I might be loosing prime, the PSI fluctuates and the pressure on my well drops?
