Hi,my name is mike and I will assist you with your question.
The issue that you are describing does not sound consistent with a failing throttle position sensor. The issue that you are having is consistent with a fuel delivery problem. The fact that this happened after you got fuel indicates that there might have been some debris at the place you got fuel and got in to the vehicles fuel system. What I would suggest is to go ahead and change the fuel filter and after doing this run some fuel injector treatment through the system and this should cure the problem.
