speedo non functional but works after restart
 

99 F250 V10 SD 4WD. When start engine and put in drive speedo does not work and trann y will not shift normally. If stop, turn off, and restart, then works fine every time. Does this randomly--no relation to hot, cold etc.
Never does it on the fly, only if engine has been off a while.
Any suggestions as to what to replace??
thanks. can reply to : banjo@onemain.com.
