AutoPage RF-310 Alarm System vs Ignition

Hello, I am having ignition/alarm problems with my 1958 Plymouth. HISTORY; the car was just restored in Utah and delivered to me here in Las Vegas. Somewhere along the line, the supervisor elected to install an AutoPage RF-310 alarm system in the car. Between the time the alarm was installed and i actually took delivery was about 3-years. And (in my view) ever since that alarm was installed, I've had battery, alternator, car alarm and starting problems. In the last 3-months Ive had to replace the battery, the alternator and now the v-regulator. The primary failure mode that I’m experiencing right now is when I’m driving the car; typically in hot driving conditions (100-110 degrees) and at a slow speeds; that is when the car dies or shuts off. I get NO sound, no visual clues; nothing. The car simple shuts off. To-date, i have not been able to isolate the failure mode down to one circuit. Recently, I took the car to an ASE certified auto shop here in Vegas and they informed me that in their viewpoint, they believe the Voltage Regulator (VR) could not handle the amp demand and was cycling on/off in excess of its input/output capacity. They also believed that the amp gage in the dash was improperly wired causing a drain on the circuit. So they swapped out the old style VR with a new(er) digital model and strung new wires to the alternator and Amp Gage. Now the amp gage indicates properly whereas before it was erratic at best. I paid the shop, hit the gas and drove out the garage all smiles. My smiles ended 2 miles down the road when to my horror the car died right in the middle of a 4-lane, 4-way intersection. When I say died, I mean it died. I put the car in PARK and I turned the key and there was no starter spin up, no ignition, no spark, and no nothing. A few minutes later, I tried to start the car and it started normally. Talk about frustrating.. On the way home, an airman from Nellis AFB stopped me at a light and said my brake lights were inop. That didn’t make sense because at the shop we checked the lights using the key FOB and the lights all appeared to work fine. I got home and pressed the brake pedal down and all of the lights (brake included) worked perfectly. I clicked on key FOB to checkout the alarm systems On/Off operation and everything appeared to work as advertised. I elected to perform an amp check on the battery and it checked good. Two weeks ago when I checked the battery I found a 3.10 amp drain at the battery. WOW....no wonder my car battery was dying so fast! 3-amps versus a 60-amp battery mathematically doesn’t add up. So I rechecked those readings yesterday and again last night and my meter indicated 0.01 amps. Excellent! These were the readings after the shop replaced the VR and rewired the amp gage. So now I’m left wondering; can the RF-310 car alarm simply shut the engine off or kill the ignition system with no visual or aural indications or warnings? And even while the engine/car is running?
