08 hyundai santa fe losing power while driving.

08 hyundai santa fe losing power while driving no lights on the dash are
coming up either. The ABS light is on and i have turned it off and back on
and it doesn't seem to do anything. its like it is jumpy feeling like it's stuck in
the manual shift mode but not! The rpms never fluctuate and the car has a
full tank. I drove it to work and it was fine. I drove it from work to home and
that's the first time it has ever happened. I get in it the next day to work we
go and it drove like their was absolutly nothing wrong with it.... leave work
and it starts out okay and then I stopped at a stop sign and went to go and it
started loosing power behind it again. Stop at the gas station worried about
driving further and then I decided to go the back way home just in case and it
drove like nothing had ever happened. I have my boyfriend drive it and it was
jumpy and loosing power on him. Clearly we aren't car people and just need
some help.
