Just to be clear, everything was working fine with the previous receiver?

Thanks for the reply by one and all. This has been very frustrating and I appreciate everyone's input.

* My Steering EPAs are backed off from lockout per suggestion so the servo should not be straining.
* I am only having issues with my stadium truck. My buggy uses the same transmitter but diff. types of electronics with no issues ever.
* The issue can occur on any part of the track at any time. I did have runs where the truck "passed out" at the same corner 3 times but that was one day only.
* I constantly keep the transmitter batts. charged around 5v and have not noticed any affects on the issue.
* Sometimes the truck will "pass out" after a hard landing. I tried checking all electrical connections. Nothing looks amiss.
* If I stay below 70-80% throttle all seems well but that is not scientific.
* The previous receiver died suddenly meaning the truck just quit and the receiver power light just weakly flickers. This happened when the truck was having its issues as well.
I figure it is something with either the ESC or the servo at this point. You should not have to add on BECs or glitch busters if you shell out 100s for components what the heck??

Just for grins, I would replace all the connectors just to play it safe, there was a local at my track who had a cage style bullet which was over compressed and sometimes it would lose the connection after a large jump causing the ESC to shut off and momentarily reset itself... after a few moments he could drive again once the ESC finished rebooting. After he replaced the connectors the problem went away.

That makes sense. In fact I thought the battery connection was the issue because they were loose originally. Re positioning and checking the tightness seemed to make the problem disappear for a few days but it came back.
I will try replacing the plug. BTW I use XT-60 connectors which are tight and never gave trouble. I may switch to direct connections for this truck. Perhaps the connector is bobbling around causing issues as well.

Checking back in, Im still troubleshooting this monster. I replaced the connector without any change. I am now going to swap the esc for my old trackstar turbo and see. If that doesnt work then Ill replace the servo

The trackstar made no diff. Swapped the Reedy HV servo for a cheap Protek and I moved the antenna wire from looping around the servo to a more isolated area. This seemed to work for 2 packs so far. If it stays glitch free then it was the servo or antenna routing.
