I have 12 hours on mime now. So far it has quit 2 times. The fuel pump shuts off. If it sets for a few min it will start and run fine. Has anybody seen this before?

No but you should have a 2 year/12,000 mi warranty. Get her in stat!

Def sounds like lift pump.

Fuel pressure is a gauge high on my list.

I have about 4500 miles on my 2019 ROXOR. I have found that occasionally, when I accelerate hard and for an extended time, the engine dies. (Think about accelerating onto the freeway.) If I turn the key off, then start it again, it will keep going. This doesn’t happen all the time. I live about 1/2 mile from the freeway and I suspect that this only happens when I get in and take off immediately and the engine is not quite up to operating temp. Doesn’t seem to happen if I’ve already driven a few miles.
Anybody got any ideas?

Thanks guys! I’ll check it out. I have a scan gauge, but I don’t think it does fuel pressure.

They do but you might have to program your unit.

Good morning, I have a 2019 and having the same problem with shutting off as uncle Chuck. Changed filter no change I have a lift pump to install but, I can put the stock ecm back in and it doesn't shut off.
It seems that when I am driving hard merging in traffic, and the tach sees 2800 rpm it shuts off, leave clutch out and switch key off and back on and it starts right up.
My concern is that it doesn't do it with the stock ecm?
I have a kms ecm stage 3 and it looks to me that they are out of business.
Any help would be appreciated. I'm in Panama city Florida .I have no dealer within a few hours drive to go to.
Also have a scan gauge on dash for info it doesn't see anything.
Thanks Dallas

Allowable Fuel Pressure Range for Roxor vehicle is 5– 5.5 bar. I would check for drops in pressure in the fuel delivery system. I have seen this happen in vehicles where an anti-backflow valve was involved and it started to fail.

Is it because the tuned ECM needs more fuel? When I had problems it would die then immediately start. Always under a hard load otherwise it ran fine. Eventually it just didn’t start at all. Ended up being in tank fuel pump not supplying enough fuel/pressure for engine. But pump was putting fuel to the filter. Stock ECM might not need as much fuel therefore it runs.

The tank has a drain plug. Makes it easy to empty and pull the tank
