    CNG tuneup needed. If issue was on Patrol i would have suggested fuel filter, Plugs and plug wires.
    Even if you are on the right track, you will get run over if you just sit there.

    go for a cng tuneup and also check if airfilter box(frypan) is not letting extra air flow in to carb, distributor timing and cng kit is not set extra economical setting(which does exactly opposite when you need accleration) and distributer timing is properly advanced.

    if problem presists

    get the carb cleaned(rare) or coil changed.

    I was about to suggest the same
    The best car safety device is a rear-view mirror with a cop in it.
