So here’s the scoop! I’ve tested this on multiple F886 and on multiple programmers with PBP2.60 and PBP2.46.

Bruce your right!
“If only RB3 causes your problem, then I suspect you're simply not getting LVP turned off.”
PBP 2.60/melabs programmer 4.23
Code:
@ DEVICE INTRC_OSC_CLKOUT,MCLR_OFF,BOD_OFF,WDT_OFF,LVP_OFF  
OSCCON=$70
ANSEL=     $00
ADCON0=   $00
CM1CON0 =$00 
CM2CON0 =$00
Program, Read Code, View – Configuration
Low Voltage Programming --- Enabled
Must tie RB3 to Vss ... Remove Vss on RB3 MCU stops after about 5sec.
Digital output voltage on RA7 low

PBP 2.46/melbas programmer 4.23
Same code
Program, Read Code, View – Configuration
Low Voltage Programming --- Disabled
No Vss needed on RB3 ... Digital output voltage on RA7 correct

Hobbyist was near wits end! Now What?
