Cranks fine when cold but after it's been running awhile it's hard to start when you cut it off and let it set a few mins??? Cranks but doesn't run right for the 1'st few seconds then clears up. Any ideas????? Thanks in advance. richard

Vapor-lock. Todd at Hunterworks has a thread somewhere about pinching-off some line at the fuel-rail. I'll try to find it.

My vote is the throttle position sensor, that is down by the gas pedal, seems there might have been a bad batch.

Mine starts and runs best if I don't touch the gas peddle until it levels out.

THERE IS A ECU REFLASH FOR 2011 & EARLY 2012 MODEL RANGER'S & RZR'S THAT KEEPS ECU POWERED UP FOR 15 MINUTES AFTER KEY IS TURNED OFF REASON FOR THIS IS ECU PURGES FUEL PUMP TO KEEP FROM VAPOR LOCKING MORE NOTICABLE ON RANGER'S BECAUSE OF ENGINE IS INCLOSED MORE. JUST TAKE TO NEAREST DEALER TAKES ABOUT 15-20 MINUTES

T-ROY I'll have to check that out. Mine just started doing this over the weekend at TWRA. Never happened before. I did some research RZR Forums is saying to wrap the fuel lines in heat reflective tape. Gonna try that as well.

I have the same problem on the Jeep and have had to wrap the fuel rail and injectors on it as it vapor locks while wheeling in the summer.
