Well would you be able to tell me why i can put the tune in my truck and itll spin the tires then after a few minutes it can't?

I recently got the intune i1000 and when I put in a canned tune it runs good for a short time(as in I can do burnouts ) but after I drive litteraly make a minute down the road its not the same. Anyone else have this problem? It is on an 02 silverado
