Recently had this issue 2 days ago, replaced all 4 coils, new spark plugs, new throttle position sensor and reset E-23 code. Got lift running great then it would go into limp mode about 2 min after running and would only run up to half throttle even when pedal all the way depressed. Wiese tech. Came out reset code and lift was fine. Now it's monday morning and it's back to not starting and blowing propane out of intake... Anyone had this issue before? If so what could be the issue.. Thank you in advance!
