Motor power surge while driving

Hey guys, I have a 99 f250 with about 187,000 miles on it. I haven't had this truck very long but recently, it started to surge when I'm accelerating. Usually happens if I'm taking off at a slow start. I can keep the pedal in the same spot and it will surge foreward and the rpm's will jump anywhere from 50-250 then fall back down to normal...it will keep doing this until I step into it or get up over 60. It seems seems to be more noticible at speeds up to 60 and before it hits o.d. Other than that, it runs fine, idles fine, and if I get on it from a stop it doesn't miss a beat. Only happens when I'm taking it easy on it...maybe it just wants to run! I changed the fuel filter yesterday thinking that may be it but its not. Any ideas would be great. Was pretty efficient on working on my duramax till it burnt down but this is my first ford!

Thanks.

I was driving home tonight and everything seemed fine which got me wondering...the last several days that I have been having these problems the temperature has been in the upper 90's. Tonight it was mid 70's when I came home and the truck ran fine. Could be just a fluke but im not sure. It's supposed to be cooler the rest of the week so I will see if it still does it or not.

Maybe has a symptom of a cps but wont it usually have more of a hiccup or a "miss" and idle rough with a cps going bad?

Ok so I drove it today and the temp is in the lower 70's. No problem at all, truck ran fine. Seems to start doing it above 85 or so.
