Car cranks up and drives till come to stop?

Hello everyone im reaching out to see if anyone else has had the same issue as I am. Car has ran great since got it till just couple weeks ago. So when I was driving one day it was running fine than out of no where it was going than it started going slow and as I pressed the gas it was just revving up n not going. So I pulled over checked fluids and everything was good I got back in started car up and it took off like should. When I came to stop at light and went to press gas it just revved up and moved slowly I pulled over again and turned it off and inspected it again and didn't notice anything no leaks no smoke or strange smells. I got back in car started it up and it went like it wasn't just driving weird. But soon as I slowed down and try pressing gas again it didn't catch n go like should. I turned it off and restarted it and it would go like normal. I replaced solenoid A&B and car was fine for couple days than my issue started up again. My trans fluid is at correct level no leaks or burnt smell. Now car cranks up n goes until I start to slow down or come to complete stop than I have to restart car and it will go again like should. But if I stop an than try to go it just revs up. I would have to shut it off and restart it to go again. I'm really hoping it's nothing major and something simple to fix. Unfortunately I am not able to work due to a medical condition I was recently diagnosed with and have limited funds. I had to leave my job and am limited on what am able to do with car. I have deprived myself of sleep and everything else putting all my time into getting issue figured out. An reason why is the car has a very special meaning to me I inherited the car from my mom who passed away and it's only thing I have left of her. I would take rides in car and just drive I felt like she would be riding with me during my ride. I'm hoping that I don't need to rebuild it or replace it because like I said my funds are limited and don't really have strength to do that. I was diagnosed with Lou Gehrig Disease and it was hardest thing to have my doctor tell me that there's absolutely nothing in the world anyone can do for my condition because they have no cure. So any advice is appreciated and greatly excepted and thankful. Thank you for any and all information on my issue. Thank you everyone in advance.
