Help w/ pole that spins one way then the other

Hi this is actually a 2 part question: I'm working on finally getting my ayeshas on spin pole and I find it both scary and challenging. I'm proficient on spin pole (except for moves where I have to face the floor such as caterpillar and ayeshas). I can hold true, cup and elbow ayeshas for long periods of time so I know I have the strength. When I try to do them on spin pole, my pole kind of stalls and goes one way then the other. Maybe because I'm nervous and not giving it enough spin? Any advice would be greatly appreciated!
