its possible your fuel lines somhow got air in them and it is locking up because of it, however it is also possible that your fuel sensor is failing, there are alot of possibilities. i would take it up to the nearest goodyear or other mechanical shop. i say goodyear because i trust the one in my town with just about anything, though it may not be the same where you are
