I have a Vertical BMX bike. My problem started small. Usually when I started from a stop or put a lot of pressure on the pedals going uphill, my chain skipped or something to that effect. Now it gets to the point where I barely ever get anywhere pedaling. What's happening? I've tried moving the back wheel further back, but that doesn't seem to do a whole lot. Any other suggestions as to what the problem might be and how I fix it?

Stretched chain and/or what's called sprocket and chainring in the regular bike world. In BMX-speak often called driver and sprocket.

Once you've figured out what, it'll have to be replaced. These parts wear together to fit together. Start with a new chain. If you still get skipping, replace the thing at the rear. If you still get skipping , replace the front.

[LIST] Lubing is problematical ... a temporary "fix" is to try to seep some silicon spray lubricant into the mechanism to un-gum the grease ...
THAT would be a temporary fix ... BUT, it's easier to just plan on buying a replacement Freewheel which will typically be less than $20. FWIW. I recommend ACS CLAW Freewheels ... they are available for use with standard 1/8" chains or 3/32" "Road" chains. check www.Danscomp.com if your local LBS doesn't carry BMX "stuff" OR to use as a reference ...
