Unit was running & operating fine. Shut it off & 5 minutes later wouldn't restart. Battery is good, key on & instrument panel lights up, wont crank or start. This lift has the electronic controls for the lift/tilt/side shift. I put power directly to the pump & jumped the starter & it will start & run but there is no lift/tilt controls. All fuses are good. This one has me stumped!! Suggestions anyone??
