2019 Roxor Power Surge

[RoxMan]

Good Morning! I have a 2019 Mahindra Roxor that I have addressed many issues with. At the moment, it is quite a bit of fun to drive; however, after a while of driving, it will suddenly lose power and still drive, but it can't hold fifth gear. If you shut it off and start it it will have power but if you shut it off and then unplug the computer and plug it back in it will have even more power than just shutting it off and restarting even being able to reach 80mph with the Gillomen tune. Any suggestions or know-how would be awesome. Thanks!

Fuel filter? start simple.

 

[RoxMan]

Thanks, but I have tried that several times.

next I‘d go to checking battery terminals and grounds. No codes being tripped?

Where do I check the battery terminals and grounds? I have an Innova Pro 2 or something scanner that I have tried to scan it with, but there doesn't seem to be any codes.

Just look at the battery terminals, see if there’s corrosion. Bad terminal connections can cause all kinds of havoc on our semis. It’s usually the first place to check. I also recall that someone had a bad ground on the inside passenger side by the fuse box under the cowl. If I’m not mistaken his engine would die or a no start condition. I think it was just paint that was making a bad connection. He cleaned the mating surface and it fixed his issues.

Thanks! I’ll let you know what I find out.

Is your fuel cap venting letting air in as the fuel is used.
