Hello everybody!! I have a bobcat S160 that will not stay running at high rpms.Runs fine at low rpms for a minute or so.
Does anybody have any idea what the problem is?? Any help would be appreciated!!!!

1. Ask administrator to move this post to the Bobcat Construction Equipment forum, you may get more in put.
2. When it dies does it shout off quickly like turning key off? or does it sputter a little like running out of fuel?
3. Are there any warning light, codes coming up?

It sputters and no warning lights or codes.. It says it has a half tank, maybe the gage is wrong?

Gauge could be off, or sender float hung up in the tank - add 5 gl. clean fuel to tank and see if gauge moves and try running it.
Fuel filter could be plugged or excess water in fuel - open water drain on bottom of filter to check for water. Change the filter.
Debris in tank may have restriction in elbow fitting in top of tank - Run the engine at high RPM while watching the primer bulb close to the fuel filter, if the primer bulb starts collapsing you have a restriction in the pick-up line going back to tank.
