    SCHEMATIC1 _ PAGE1.pdf

    here's rough schematic again - sorry for the wild goose chase guys - really appreciate the help.

    Q2 is only driving the gate of some P channel mosfets. With the load attached to the drain of the mosfets, pin 3 on PIC wont drive the base - the program leaves the main loop - it resets.

    If I release the load and turn on NPN and then turn on load, it stays on.

    I was aslo thinking of changing the circuit to a double npn and reverse the logic - thus the PIC wouldnt see the 2nd NPN, but I'd like to know why its behaving this way.
