Smile 1993 ls400 weird acceleration and tranny issues

a few days ago i tried to take a trip with a few friends about thirty minutes after getting on to the interstate the car began to rev high with zero acceleration so i coasted off the road shut the engine down and turned the car backk on it ran fine for about 2 minutes then did the same thing again. the car ran flawless before this and now problem comes back every time the engine reaches running temp. i checked the transmision fluid looks fine and is full. before the car stops sending power to the wheels it shifts and accelerates smooth.????

any ideas what this could be or how i could start trouble shooting this?

This is a good read because this is one service aspect that 90-97's will require. May be relevant to yours.

Possible to swap ECU's so long as it has had the capacitors fixed and with the right ones. Have to make sure the ECU is for the correct year. This is the ECU listing:
