If your Rampage was running and then died, there may be an air pressure build up in the fuel tank. To check for this, slowly open the gas cap and listen for a a hissing sound as the fuel vapour escapes. Leave the gas cap loose and try to start the engine. If it starts, ensure the vent hole in the gas cap is not blocked.
An open vent hole is required to allow the pressure inside and outside of the tank to remain fairly equal. A blocked hole will cause a pressure differential to form, and may lead to an undesireable rich or lean condition. A postive pressure inside the tank would increase the fuel supply (by forcing more fuel through the lines), resulting in a rich condition, leading to potential bogging. A negative pressure would result in less fuel supply reaching the engine, resulting in a lean condition - higher RPMs.
Clean out the vent hole as necessary with a pin. Ensure all gas cap rubber internals are correctly seated.
Additions tips:
There are many different venting options discussed on the forum that you may want to review. You can simply enlarge the vent hole slightly or, a better venting option would be to install an aftermarket vent kit.
