FRPS or Something Else???

Randomly sputtering once today at 2500 to 3000 RPMs in first and second gear. Then on the interstate in fifth and sixth gear sputtered a little bit and did this. Wideband showed 10.0 I know it’s dumping fuel into the engine but unsure as to why. Anyone experienced this?

I drove the 9 miles home and parked it.
2.8 Kenne Bell with a lethal budget return system.

If the frps failed (bladder burst) should be fuel in the vacuum line that’s connected to it

I checked it today, didn’t smell like gas, but could have dried out since yesterday. I’ve read about electrical failure as well which doesn’t result in that.

mid say prime it or try to start it real quick and shut it down, immediately check for fuel.

have you oiled an air filter or anything lately that might have resulted in maf contamination?

No changes or oil on air filter. The new engine and fuel system only have 250 miles on it. Upgraded fuel/ blower and engine combination and just got it back to drive. Drove great until yesterday and started the sputtering and acting odd. It only does is at low throttle. Seems normal sometimes and then will start doing this. It also sprayed a little fuel out of the exhaust on starting to come home yesterday.

Honestly I know it sounds lazy but I'd just buy a FRPS and try. I keep one and socket for it in the trunk never popped one returnless but did on a Fore return which is counterintuitive. Really shitty when you do. Not waste to have one even if it's not the problem.
