I take the freeway in the morning after a cold night, power is good up to 40 then it starts to act like fuel isn't combusting, it sputters and slowes down sometimes, is arcing going on in the distributer? Could moisture be causing problems? When I take the freeway home in the afternoon I'm reaching 70 mph no power cut outs. What's going on?

Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.

I replaced the Fuel Pump, it was leaking some fuel, and replaced distributor cap, coil and wires. Problem solved.
