P0171 = System too lean Bank 1
P0174 = System too lean Bank 2
There are a variety of possibilities...bad gas, water in the fuel, plugged fuel filter, faulty fuel pump, etc. Did it follow shortly after fueling up at a strange station? Is it running poorly? Is it overheating?

there are 3 Spyders all filled up at the same station. Engine is not running hot or is not missing. When the codes first came up a strong smell of gas, but nothing else.
Should we try some fuel injector cleaner as a first step. BRP dealer is some distance away. Need to understand if we should chance going home
The strong smell of gas would worry me. I'd remove the right side body panels and inspect the fuel lines and fuel filter to be sure nothing is leaking. If that is OK (while running), you can try to limp home as long as it will go and it is not in limp mode. Please understand that there is a risk to the engine if you do. A lean mixture can cause piston or ring damage, or even damage the cylinder head. If the other Spyders had no problems, the fuel is likely alright. I'd avoid the fuel injection cleaner. If it isn't used in short order, it could do some damage. Marine Stabil or Seafoam are safer. The safest thing to do is to have the Spyder towed.
You shouldn't have the codes or the light after a restart unless the problem was still active. Could be a sensor problem, but wouldn't be my first guess without a sensor code. Not likely O2 sensors, since both would have to fail to make both sides lean (on an RT). Could be a vacuum leak, from broken lines or a failed purge valve, but they usually leave a different code. There are other possibilities, too. Could even be something mechanical. You need a dealer to go through it with BUDS to try to find the culprit. All the speculation in the world is no help at this point. It is not a common problem nor a simple, roadside fix (provided the fuel line and filter aren't leaking).
Thanks for the help. After talking with his dealer the decision was to ride home. We made it home without any issues other than the check engine lights on. Here is the strange thing. We are Canadians and this happened while we were in the US after filling up for the second time in the US. My buddy filled up one last time in Canada about 10 minutes from his home and the engine lights went out. Is it possible that the fuel is that much different? I believe the US may run more ethanol than Canadian fuels. He only used 93 octane in the US, however in Canada, 93 octane is more difficult to find and he used 91 octane Canadian fuel and the problem has disappeared. Coincidence? He will certainly have it put on BUDDS this week. There was still the strong smell of gas at one of the stops in the USA. Looked under machine and he is getting drips of gas coming out of the evap canister vent hose on the right side.

i hate, hate ethanol..I use two free apps for smartphone: PURE GAS and ETHANOL FREEcould you post the web address so i can see if any stations sell good gas here in Oregon. Thanks
