Fpr

Is there a way I can check my fpr to see if it is working or if my injector pump is going bad I have 250000 miles and now when the truck get warmed up and you get around 2000 rpm's it shuts down

most of the time when the fpr is going out the truck won't idle right, its up then down all over the place, but never really high. When my pump was going out it would run fine, but wouldn't spin over about 2k rpms.
