Sounds like the ECU may be going out. BUT, before condemning the ECU, check out the APM/TPS. The U0100 and U0101 codes indicate a problem with the CAN bus. Maybe there is a wiring problem grounding it out or causing an intermittent open? The P2135 refers to the throttle pedal position sensor (APM; inside the cabin attached to the pedal) not correlating with the throttle position sensor (TPS; mounted on the throttle body). Note that the TPS is not replaceable as an individual component.

check all the fuses both inside the cab and the engine area… check with a multi meter each one… might be as simple as a bad fuse that is like on half the the ECU… killing half the the computer… also check the conectors and wires
