Cat gus, need advise. TB45 LPG. Engine starts and idles, revs up. When you put it in gear and drive after a few seconds the warning light comes on and a few seconds after that engine dies. Restart and it will do it again. It has an analog hour meter and customer does not want to call CT DEALER. I have wiggled the harness. At idle the only way I could get the warning light to come on was to wiggle the seat. I bypssed the seat switch, thought I had it but it did it will its moving. Seems to be when it reaches its shifting speed. I'm leaning towards the speed sensor. Any body have any thoughts or am I SOL without the dealer program?
