Double check your battery supply. The only problem I've had shutting down was on the straight almost same spot each lap just before the sweeper (so yes it got ugly) after trying different things including a different receiver problem was the battery pack - cracked solder joint.

Also check the SpektrumRC site for a bulletin on the antenna routing in the TX module. I have seen two problems with glitching and or shutting down and in both instances it was due to the coax coming disconnected inside the module. It's worth checking anyway.

I checked the antenna routing on my maodule and it is on top of the board instead of being on the bottom so it looks like i will be sending it out to be fixed. Ive been using it for quite awhile with no problems indoors...this was really the first time ive tried it outdoors...could that make the difference?

Yes they should have them.
Be sure you meet the minimum input voltage of the regulator your getting. (check out datasheets with google)

HOW TO CHECK YOUR TRANSMITTER MODULE
Using a Phillips screwdriver carefully remove the case from your module and examine the antenna connection to the board:
Correct
Note the antenna coax is routed under the main radio board.
Incorrect
The antenna coax is routed over the board in close proximity to power capacitors and IC’s compromising signal integrity. Please return to Spektrum for service. In the case of Futaba Hitec modules, a longer antenna wire will be needed.
