Greetings from sunny North Texas. The washing definately got something out of whack. I recommend you get TuneECU and a chip enabled cable and connect to the ECU to really start diagnostics. The TPS is a known weak point but first you need to know if that's out of sorts before digging in. The very early bikes (2004 to 10) had the headlight power routed through the ignition barrel and that caused desoldering problems on the ignition. After 2010 Triumph rerouted power to the headlights. If your bike isn't equipped with a headlight relay bypass (Eastern Beaver makes it) check you ignition barrel if TuneECU shows your TPS is gold.
