Do you have a 2-way radio installed? If so, where is your antenna mounted? Is the antenna a ground plane or a non-ground plane type?
I had the same problem as you are describing that is the reason for the above questions. I purchased a Rugged 60 watt 2-way radio kit with antenna. I had a shop install the radio and antenna, however, they did not know s*** about how a 2-way radio works. The type and placement of the antenna is the most critical part of the radio system. 60 watts of Radio Frequency (RF) radiation can do a lot of things like give the radio a great deal of range in talk power and cause havoc with other electronics in your Talon.
In my case the antenna supplied with the kit was a ground plane antenna. A ground plane antenna needs to be mounted on a flat metal surface that is in turn grounded to the chassis frame work. The shop mounted it on the rear roll-cage with a bracket and a ground wire attached to a screw drilled into the cage. This caused a huge problem for the Electronics in the Talon.
The Talon dealer could not figure out why my talon would quite running while driving. The dash panel would act up with all kinds of warnings, some flashing - some not. I could restart the engine put it in gear and it would instantly stall. If I left the Talon alone for at least two minutes with the ignition switch turned off it may restart and allow the electrical system to reset and let me put it in gear and drive away, at least for a few miles and then it would do it all over again.
The cure was to move the Ground Plane antenna to the center of the plastic roof and place an eight inch round piece of metal on the antenna base and then run a ground wire to the top bar of the roll cage. My electronic problem disappeared completely. Turns out the RF interference was being radiated into the Talon’s computer and was causing it to go nuts.
