Limp mode and engine stalling, Codes P1172 & P1175 - any ideas?

[ARNIE R]

Had a beautiful day to go riding, so off I went.

Stopped for gas about 30 miles away from home. The bike ran perfectly until about the last ten miles. Then, it felt like it was trying to shift between 4th and 5th because the engine started surging, Next, the Limp Mode light came on and the engine became more erratic.

The bike stalled on me about 5-6 times before arriving home, in between running ok for a few minutes at a time. The Limp Mode light kept randomly popping on and off.

Pulled two codes when I got home. P1172 and P1175. Looked them up but still puzzled about why all of this happened so suddenly.

Bad gas or something else? Vacuum hoses have previously been replaced with silicone ones and the crankshaft position sensor has also been replaced once.

Thanks.
