2003 EZGO gas cart won't turn over

[lovesglass54]

We have had this darn thing "fixed" several times at Battery Source. Get it home and it runs good for a while, then start having trouble. The current problem is it won't engage when I press on the gas. Previously I was able to turn the slip drive clutch and that would work, but now nothing. I've looked online for anything that would help but haven't come across anything yet. Please help
