So I am assuming this is an automatic transmission?
"Looked for possible vacuum leaks, like hoses and PCV system"
With your eyes or with an unlit propane torch, WD40 or similar sprayed on all the connections?
I did not see cleaning the throttle body mentioned (but I might have missed it) the second that throttle switch opens, the air all comes through the throttle body and a badly gummed up one will have challenges with the transition.
Finally, check your transmission fluid (if an automatic). If low, the pump can cavitate at stops, suddenly run in clean fluid, attempt to jerk forward and cavitate again...this rarely causes a full stalling of the motor but it can.
1991 does not have the under hood 20 amp blade fuse, correct?
