John, were there any signs leading up to this incident? When did the stalling began? How long had the vehicle been running? What was the approximate temperature that day and at the time of the issue you are describing? Were you on an incline? Which motor do you have? How many miles are on the vehicle? What scheduled maint. have you performed or missed? Have you had any repairs or services performed recently? Any odd odors, sounds or vibrations recently? When was the last time you refueled. What type of fuel do you normally buy? How often do you change the oil and filter? Obviously at this point I have more questions than answers, but if you'll take a bit of your time to answer them, I can promise you positive results. Thanks in advance John F.
