I lost a roller lifter at about 8K miles, I don't like them! I ended up doing a complete over haul and went with a flat tapper. I did remove the inner spring for my initial cam break in and that is likely the difference. Yeah, what a pain in the butt re-installing the inner springs later with the motor in the car. Beats the heck out of loosing a cam though! Roller lifter just don't "live long enough" to suit me. Flat tappet or hydraulic roller is the way to go (and I'm not big on hydraulic).
