All stock sled, engine cutting out at low & midrange with check engine light coming on & off. Engine temp 127. Changed plugs but that didn't help. What's the most likely cause? Thanks

Like won't come much off idle? Check your throttle safety switch that allows the throttle to pivot back on the pin when pulled. Last week mine iced and you could pull the throttle but it would cut out and die.
If that is ok TPS connection in bag under the hood may be corroded or just have a bad connection. That will cause it to flash engine light and cut rpms.

Error code 51 is a TPS code. you for sure have an issue with the TPS. You can find them on Ebay used for around $60 bucks and then calibrate it. New are about $150 or something like that.

Did you figure out your issue. My buddy is getting an error code 51 - 10. We replaced & calibrated the ECU, but the problem still persists.
