"but it started right back up again"
does that mean the problem started back up or the engine started up normally?
Don't overlook a plugged catalytic converter. That can make it backfire, sputter, idle very smoothly but lose power at higher speeds. You might hear a smooth hiss out the tail pipe instead of the normal puffs from the engine.
