That’s very weak sounding battery. Keep it on tender charger 24/7 while troubleshooting this. Do these measurements;
1. battery power with everything off, volts = ??
2. battery power during cranking, volts = ???
3. Test for spark while cranking. What colour is spark?
4. do fuel-pump flow-test. Don’t worry about jumpering fuel-pump relay, just crank engine for 10s, how much petrol did you collect?
