loss of power on my 2008 trx700xx
#1
Just riding along on the local frozen river with my kids and all of a sudden I had loss of power and died. Was able to re-start but would stall. Was able to get it home and now turns over but does not start It's fuel injected. I was riding for a good half hour. Can't understand why?????

Welcome to the forum, and merry Christmas.
I'm not that familiar with the xx but maybe I can be of some help.
How did it shut down when it stalled? Did it surge and cough a bit, or just die? Do you have a check engine light, or anything blinking on the dash?
Anyway, I would check the obvious things first. Make sure it is full of fuel. I'd also pull the gas cap, since if the vent is obstructed it can cause loss of power and the engine to stall because air can't enter the tank to take up the volume of fuel as it is burned.
Beyond that, an engine needs compression, spark at the proper time, and fuel to run. Figuring out which one of those it doesn't have would be the beginning of diagnosis.
Checking for spark would be the simplest, so I'd pull the spark plug, put it back in the boot and ground the body. Then crank it and see if there is spark.
You would probably notice the difference in how it cranks if it had no compression at all, but a compression test might be a good idea.
Fuel wise, on some engines you can pull the injector from the intake and see if it sprays while cranking.
Rincons have a little sub-tank in which the fuel pump resides. I don't know if the xx is set up that way, but if it is there is likely a sock type fuel strainer in there that can clog.
