Replace you Gas Cap and see if it will not stop this Problem. If the Seal on the Gas Cap is Bad it will allow air into the Tank and will cause this Problem. Please Rate My Response! Thanks!

Bad sending unit attached to fuelpump or most likely a crimped or chaffed wire to it, either inside the tank or outside.
