Jumped the battery after car sat for awhile then

You'll need to check all the safety switches. Probably one in the seat, one for the mower engaged, one for clutch/parking brake engaged, possibly one for reverse gear selected, and possibly for position of the steering arms.

Have u ever went on the internet about your car.there may have been a recall on your alternator or other people with the same trouble your having.I had a mercury that I to replace the alternator three times.Come to find out there was a recall on my alternator because of how It sat in the engine.the wires running to it kept getting burned out by the powersteering belt.Just a thought when u keep replacing the same part.

IF ITS CRANKING AND YOU HAVE GOOD FUEL PRESSURE I WOULD CHECK YOUR TIMING BELT TO SEE IF IT IS BROKEN OR STRIPPED OUT. HOW MANY MILES ARE ON THE CAR?

have the alternator checked. if the alternator is not charging the vehicle is only supplied with what power is stored in the battery. once the battery is dead there is nothing to charge it

It may be a bad ignition switch.

Also, It could be a fuel pump, remote chance. A fuel pressure test would prove if bad. Should have 40 psi of pressure.

Any warning lights on, on the instrument panel? Check engine light? Or, they come on after the stall?

I ran into the problem and it was corrosion on the battery terminals. on the inside against the battery. also check the the terminals for good connection.
Stay warm

replace the alternator

the battery is located under the rear seat, check battery connections. if connections are tight replace starter.

i had hte same problem wiht my 95 it sat for two months and it did this either youhave a couple of dead cells in your battery or you alterator could be going bad wither that or a nasty combination of them both
