Color of wires in question would help.

No idea about the loose wires, but your warm start problem sounds a heck of a lot like Vapor Lock. After you turn off your engine, the heat actually rises more for 10-15 minutes. This heat can vaporize the fuel in the lines and lock the line until the temperature lowers enough to re-condense.

You can alleviate this by thermally wrapping any exposed fuel lines, replacing any missing/holey heat shields over the manifolds, etc.

For the wires, as the poster above me said, we need wire colors...
