My kids have never done that but ideas that may be helpful:
1) She may have poorer control when she is tired. Make sure she has an early/good bed time and she goes to bed on time each night.
2) Does she do that everywhere? Or is it around you but not at school or at the babysitter? Sometimes kids do things only around mommy!
Try a reward board- put up a sticker board and you two can come up with prizes/rewards. 2 points = play a game with mom; 4 points = extra story at bedtime; 6 points = extra 20 minutes on saturday night watching TV, etc.
Don't take points away but give a point for every 30 minutes (or whatever; every 2 hours, etc) for no tantrum. Keep praising for no tantrums.
She only does it when she is with myself, dh, or her sister but it can happen at places outside the home if we are with her (friend's house, family, etc).
