O/D light flashing, added a bit of gas, then check engine soon light came on

What is your question?

I added $6 worth of gas and 2-3 mins later noticed the O/D off light flashing. Drove 6 miles without issue other than the OD flashing. Parked and started it up 5 mins later. OD light still flashing drove 3-4 mins and Check Engine Soon light came on. Turned truck off for 1 min. Started it and drove the 6 miles back home with OD flashing and check engine soon steady on, no noises no bucking. Just suddenly could not accelerate more than 10-15mph. Made it home, parked and haven't touched it since.

What makes this problem better or worse?

Nothing, this was sudden right after I got $5 worth of gas
