could a PMD be all my problems?

[Riddle_3d]

slightly hard start
cruise kicks out under any load, wont reengage until you disconnect batteries
occasional limp mode
code 36- injection pulse width error-time long
the worst of it all though, wont shut off with key, you have to disconnect the engine shutoff solenoid to kill it. its been relocated, could this all be a pmd?

I lean towards bad ign switch for some of your problems.ie failing to shuttoff.
Sounds also the fuel supply ain't up to par either.ie pooped LP and/or OPS,
And ofcourse the PMD could be getting sick.

You ever try disconnecting the OPS?

Not shutting off is a messed up wiring issue, PMD cannot do it.
