I installed a sensor on the fuel rail via schrader adapter and an oil pressure sending unit. If anyone does this get a 2 wire unit the fuel rail is not grounded well enough to supply negative to the sensor I had to clamp a ground wire on it to get it to work.
Anyhow I drove it enough so it started cutting out again, it maintains VERY GOOD fuel pressure and the voltage going to the pump after the inertia switch is constant.
If all the gauges were cutting out I would think ignition switch. The tach cuts out completely when it "bucks". Normally I would think cam sensor or crank sensor but being a 3.0 those are the first two things I replaced when I bought it last year.
It is getting a 5.0 but again this is an incredibly powerful 3.0 with less than 140,000 miles and I want to sell it as a great motor. I really can't until I get it running 100% I'm that type of guy.
Here's a pic of the setup. Oil pressure is actually fuel rail pressure and voltage is after the inertia switch. If the V had dropped the gauge would have flatlined.
