Will not accelerate

It felt like I was trying to go over a barrier as my car would not go forward but there was nothing there. I had just driven 50+ miles on the freeway and came off the exit and stopped at the light and when I tried to go again it felt like something was keeping me from driving. Like my emergency brake was on or something. Which it was not I never put it on. I was pulling an empty utility trailer 5 x 10 and I thought maybe The tongue had come off and was dragging on the ground preventing me from moving but I checked and it was still okay. I had no warnings or any sign that something was wrong. The guy behind me tried to drive it and couldn’t move it either and said I should at least try to get it into there park and ride lot and get it off of the road. So I slowly drove over it seem to disengage and then it seized up again, so I just waited for a tow truck. The tow truck driver noticed some kind of noise or something on the left front tire area. I just had my brakes fixed so I didn’t think it had anything to do with that. Is there any other information that you would need? Because I am so perplexed I have no idea what to do. Thank you for this site.
