Vehicle misfires sometimes,Occasionally dies Tach and speedo go dead will not restart until the key is cycled fully off then back on Odometer reads only lines until restart then quit working all together,Intermittent Heavy Stumble on acceleration not a misfire more of complete loss of power momentarily then comes back on. Set various codes for All the above sensors one at a time without check engine light. Has freeze frame data sometimes. Code and data clear on first key cycle. Crank,TPS,Knock,cam,and MAF sensors all test good. Battery 12.6 volts key on,14.2 volts running,Replaced coils and secondary O2 sensors, EVAP monitor will not set. Never the same code twice. All symptoms clear up for a day or two then come back one at a time never at the same time. Checked grounds and commons for voltage and resistance. I suspect PCM ground or PCM power feed. Possibly on the VSS circuit. Any help would be appreciated. Thank you.

Has anyone heard of the ignition coils made by motor craft beibg defective ?

I have checked connectors and coils also spark plugs
What else can I do

The first time it happened, when I went outside in the morning the radio was on and would not go off even with no key. Other times the front blower would be on or the ding warning would go off with no key. I finally realized the connection with rain after a couple of dead batteries and now I have to cover the front of the car with a tarp so that something doesn't get wet any time it rains. Has anyone had a similar problem and is there a repair?

Checked with a Valve Guage Tester and read Late Ingition Timing
I have checked for leaks
Coil on plugs good
Put new spark plugs

upper hose hot lower hose cold thought it might be a blockage changed radiator still no heat
