I was driving down the highway and all of the sudden my car would not accelerate, however my car was still on. An older gentlemen stopped to help me and made sure all the wires were secure and then my car continued to go. Not long after, I went through an intersection and my car once again did not accelerate. After 5 seconds it then clicked into gear and was fine. I have been told it might be the fuel pump, someone also suggested connection to the motor. Please help!! I'm a college student and I need to get home safe for the holidays. Thank you.
