It sounds to me as though your fuel tank needs to be flushed out. Even with a new fuel filter they can clog down enough to maintain flow but not have enough flow for your engine.

Hey Cap'n, all the heat and A/C is actuated by the controls and these controls are ALL vacuum actuated. Make sure you have vacuum to the controls from the engine. There's a 4 inch round ball under the hood on the pass side near firewall. This ball is the vacuum reservoir, must have vacuum to and from then thru the firewall to said controls. If there's vacuum everywhere, it HAS to work properly. Check all vacuum lines for leaks, cracks, connections, all the above.
