. . . Listen to all the suggestions here but would a weak spark cause this problem like immediately turning from downhill to going uphill? . . .
Voltage required to jump a gap increases with the air pressure at the gap. Turn from downhill to uphill, the governor opens the throttle and more air/fuel mixture is drawn into the cylinder. Increased cylinder charge results in more compression pressure thus more voltage requirement.
