what is wrong with my 2004 hyundai sonata ? i'll be driving for maybe 20 minutes and it'll buck and suddenly the rpm's will go up and then back to zero and it'll sputter and cut out. After 5 minutes or so it'll start again and sometimes cut out again ??

Maybe plugged cat..but that's a wild guess, a 2004 shouldn't need a catalytic convertor unless you have very high mileage and use cheap gas from convenience stores
