Next time the engine balks, try opening the gas cap for a second, then try it again. If the cap does not vent properly, it can cause a fuel-shortage response. Use a spare key and keep the engine running, because a short warm-up time and engine shutdown can confuse the fuel injection system badly. That mistake alone can cause hard starting, with no real malfunction present. If opening the gas cap for an instant does fix the problem, just clear the vent holes in the gas cap.
