I had to drive to Columbia Mo yesterday to pick up a belt for my Commercial Mower, been waiting for one from my dealer, Oreilly's crossed referenced one and I went to pick it up. Car ran fine till I got to Columbia, I was go thru a round about and when I came out of it I applied some throttle and peddle was dead, check engine light showed up on the dash. Luckily I was just a 1/2 mile from Oreilly's and limped it there. I didn't have my computer with me to check the codes so I had them scan it. Here is what showed up.

P0178 FF sensor low circuit
P135B Ignition Coil Supply Voltage Circuit 2.

They tried to reset the code and no go. I had my wife come and bring my HPTs so I could check and possible reset, nope. My Chevy dealer was less then 3/4 mile away so I limped it over there, luckily there were some painters there I knew so they opened the door so I could leave my car for Matt Jennings to check out, he's helped me do a few blowers and is really good at diagnosing electrical issues. Its a DSX sensor which I haven't heard of anyone having issues with them and the sensor has been on the car since February of 2022. Not sure what's going on but guessing it's got to do with the coil. I believe the sensor gets it signal from the number 6 coil so I'm guessing the issue starts with that coil.
Has anyone else had this issue?
