Good Day,
my brute is acting very poorly.
will start up fine, idle fine. will run fine for about 3-5 minutes then as i continue to drive and she starts to loose power and misses/backfires with any increase in throttle. As if in LIMP mode.
will still idle fine and run fine at slow speed. but will take no increase in throttle.
Had it to the shop, they say fuel pump pressure is good.
Also no codes.
Only thing i did prior to this problem was replace the drive belt.
I have no belt light indication. I have reset the belt light as per manual.
I am at a loss here.
Please help

 

Really interested to see this one. My buddy's brute is doing the exact same thing and all he did was replace the belt as well.

 

Sounds like your fuel pump is choking due to clogging.
