Auto Transmission Problem ~ 2000 Toyota Tundra

Hi all I have a 2000 Tundra with 138 k mi. I was driving and suddenly the truck started losing speed but the engine rpm same or higher. I stopped and restarted and the truck started off fine then lost speed. Now the only way I can make it move is to turn it off, then on again and it will go a short distance and will just roll to a stop. I’m thinking I have a bad selenoid but don’t know which one to replace.
Is there an OBD test and code for individual selenoid. I can just see a 700 code now. Is there one selenoid that fits the behavior described?
Any info that will lead to a fix, is greatly appreciated. Billgra

Does it downshift, can you tell what gear it's in and which gear does it get to? What speed do you get to before you start losing speed?

Did you check your ATF level?
