Check engine and transmission light comes on

[Farmman60]

Sometimes I get the check engine, check transmission and stop engine light all coming on at once for a few seconds. they all go off but I noticed that the engine power is 0 during the time the lights are on and the coach slows down. The engine diagnostic shows that I have low voltage to the throttle sensor. I changed it out and the problem still occurs. You can stop the engine and let the system go back through its per-start check and then restart it and it will run fine again for a while. I am looking for suggestions on how to find the problem and fix it.
Thanks

Check the harness to the throttle sensor back to the computer. Any knicks or connections should be addressed (cleaned or repaired).
