Narrative:

After climbing; engine starting to sputter. Pulled carb heat; seemed to help for 2-3 minutes; then sputting again; switched tanks; again seemed to help for a few minutes. I had a highway directly under me with only one car in sight; which would easily be passed under me; if I had to land. Then engine really went to idle; so with the clear road I landed on the road and pulled into the next approach. After inspecting the plane; no damage to be found; everything looked normal; I thought I might have had a vacuum problem; opened the gas cap and retightened. I then started to plane; ran fine; do run up and no problems. Then I turned the plane around and started again and run up was normal. I could see to approximately five miles each way; so with clear road; I took off again heading straight for the nearest small strip to have a mechanic look it over. It started to sputter again on downwind leg; but I was able to make a normal landing and taxi. I assume the mechanic may find a carburetor problem or debris in gas? Thank goodness my flight instructor made me do so many power out situations!
